Thanks for saving me. And I admit to old.

IIRC, I joined both DLSR and SG in 2001. Perhaps because DLSR seemed to have more information pertinent to my particular networking concerns back then, my interaction here decreased to less than sparse. Thank you @Philip for supporting the notice about Broadband Bulletin.

tHE_One: are you comfortable that adding this setting on a Win2k machine where there are multiple resources on the same IRQ will not cause some other functionality that has its own (larger) RAM allocation to end up with less?

TIA

If I understand the conclusions of the Nexland router flail we had here recently, then the following is true. If your PCs are at 1500 and your router is at 1492, then, for most low-cost routers, you will get fragmentation on uploaded WAN data. LAN data rate will be maximized, and downloaded WAN data ...

Kirby Smith

Thanks for the update Bob. I still plan to eventually experiment with Verizon to check its WinPoet limitations, and possibly thereby infer its PPPoE max MTU limitations. Unless someone here already knows that Verizon DSL will work with PPPoE at 1492 and save me a bunch of configuation and experiment ...

Kirby Smith

Good luck getting the search engine on this site to look for 3-letter acronyms, which most of ours are, e.g., MTU, NIC, and TTL. I don't know if this is a limitation of vBulletin or a setting of the moderators.

I had actually tried the ping commands I hadn't previously known about on my work NT4 PC last night. I thought I had sent an addendum to this thread on the results. In a system that has nationwide LANs, WANs, routers, frame relays, T1 lines, etc., but no PPPoE links I assume, the max ping packet ...

I have another instance of Win2k on the computer that is available for an emergency repair by changing the boot order. I don't think this instance has had any Ethernet meddling. I can install WinPoet there and test while leaving my main Win2k environment undisturbed. This will require also ...

Kirby Smith

I was so impressed by the communication stability improvement with the Nexland router over WinPoet I hoped to never use WinPoet again. Fortunately for the future of this proposed test, WinPoet is still installed on my home machine, just disabled, although I will have to rediscover just what I ...

Thanks rm. Fascinating. And my education via this thread just keeps going and going and.....

I don't think the absence of a "tunnel wrapper" in the RFC necessarily keeps DSL providers from inveigling Wind River into adding such a "feature." I imagine you can question "rmrucker" more concisely on this subject than I can.

Bob:

My question doesn't relate to fragmentation, but to how Verizon's servers manage to deal with packets which may or may not have this Tunnel Wrapper included. Does the packet just get passed along to the ultimate destination, say, Speedguide.net, where the wrapper is somehow ignored?

WinPoet is equally quirky. It uses a "TunnelMode" value which whacks several bytes off the packet size for a "Tunnel Wrapper" in addition to the PPPoE wrapper. On some ISP's, the wrapper is essential to the connection and cannot ...

Did Nexland provide an estimate of when the official reply would be made?

kirby

Kirby Smith

Yes, thanks for the persistence. And I guess thanks to Nexland for responding to it.

Kirby Smith

and Bob hasn't reported Nexland's answer on why they use MTU = 1472. I conjecture one of the following is true:

a) No one there remembers why it was 1472
b) They internally disagree over the proper MTU size
c) They are trying to find out if all PPPoE ISPs conform to the RFC before answering
c) They ...

Kirby Smith

I ran the Optimizer at 1472 after setting the router to 1472 on the LAN side. All seems well. I haven't tested exact performance, but as I didn't have a speed problem before, I probably won't notice a vast improvement.

On pushing the "Apply Changes" radio button, I got a message window that ...

Oh that they have already told me. Your LAN MTU SHould match your WAM MTU, if not all SOHO routers (Anything under $1800 they said) would fragment the packets.

A quick test this morning using the Optimizer confirms this. The highest unfragmented packet size was ...

Kirby Smith

If the optimal WAN/LAN value is 14XY, the order in which I change parameters should be what? Let me guess the following:

a) I shut down my ADSL modem and change the Nexland WAN value to 14XY, unless XY is 1472 where it is now.

b) I change the Nexland LAN value to 14XY. When I hit the "change ...

Kirby Smith

Thanks. Looking forward to the information, from which I hope we can determine what MTU should be on the LAN side.

If we don't know what Nexland's definition is, then we don't know what Nexland "MTU" value will get us to _our_ definition of 1492 + 8 = 1500. Or, to put it another way, I don't know what Optimizer MTU value will set the PC packets to conform to a given Nexland MTU value. All this, of course, begs ...

Kirby Smith

Any idea what these 20 bytes are that Nexland is asserting are needed, which I interpret to mean they are packing on top of the data and its header?

I am not attacking the Optimizer or you. The Optimizer looks extremely useful and well laid out. I'm sure it does what it shows. I am trying to ...

The following question and answer was found in the Nexland technical forum.
***************
Q. MTU size is only 1472? I just got the Pro400 and for PPPoE your MTU size is only 1472. Are you looking into changing this to 1492?

Answer from Active Support;

The Pro400 has MTU Discovery and takes the ...

Kirby Smith

I have examined the optimizer. If I follow your directions, I expect to end up with an MTU=1492 LAN connection and an MTU=1472 WAN connection. I don't know if Verizon servers will entertain 1492, although I suppose I could experiment. I will have to recheck the Nexland manual to see if the 1472 is ...

Kirby Smith

Does this optimizer know what is happening upstream of the PC? And in any case, even if the PC settings are changed, the router might need tweaking. I realize your generic answer is needed for the no-doubt-endless times some variation of my question is asked on this site, but I would like to know ...

Kirby Smith

My Nexland ISB SOHO router reports that the WAN speed is 1472 (on a PPPoE connection to Verizon) and that the LAN connection to my PC is 1500. These are either default or negotiated, I'm not sure. Speedguide.net TCP/IP Analyzer detects 1472, as expected, but suggests 1500. I assume it cannot detect ...

Kirby Smith

Because you got a message from the game and not from Tiny, I suspect a rule you already have is what blocked some message or ping from the game server. Otherwise, Tiny would have asked permission for you to send, or for you to receive. I suggest you find out what the game uses to setup a connection ...

Kirby Smith

Can't ping the servers? Did you block ICMP in a rule? If so, you may want to be more selective about which ICMP modes are blocked.

You can temporarily disable a rule by unchecking it. Then run your program and see what Tiny asks permission for. You have to be in Medium security mode for it to do ...

Kirby Smith

touser3:

If you have Tiny on "Medium" security, it will ask you about any in/out connection that you don't have a rule for. If UDP are getting through without a popup under Medium security, then you must have set up a rule to allow it.

Generally, when Tiny asks permission for something and you ...

Kirby Smith

As I understand it, your trusted address should be 127.0.0.1 (i.e., your computers host name) and the IP addresses of your router and other computers on your LAN (if any). I think the mask you showed would open up a lot, but I still have some reading to do on IP addressing.

Anyway, your netbios ...

For WinNT/temp issue, I just added regular user read permissions to the permissions list. TDS-3 didn't false report after that.

I use TDS-3 and love it. I have noticed only two minor problems that I assume DiamondCS is working on. These may apply only to Win2k.

a) Execute Protection seems to work under an Admin group user, but not a User group user. I was unable to find a registry entry or file relevant to ExecProt that had ...

I suggest waiting for two more work days to pass. However, Nexland does allow returns for any reason, so you should have no trouble returning it.

Try Nexland support. They seem to respond to questions very quickly (compared with Ati, say).

kirby

Kirby Smith

Sorry, but your questions exceed my knowledge. Are you trying to enable remote configuration of the router? Due to security issues seen recently with other routers, e.g. Cisco, I password protected mine, and as far a I know, it is only accessible from within the LAN.

You also seem to have a ...

I have a Nexland ISB Soho router I learned about on this site. The Soho does PPPoE much better than Verizon-supplied software. That alone would justify its purhase.

I use this router with only one computer. It filters out a lot of junk that would otherwise have to be processed by Tiny, with ...

In my case I don't think Tiny sees them. I think they are swallowed by my NAT router. I've had all ports above 5000 blocked with a notification, and haven't seen one since I installed Tiny. In fact the only thing I have ever seen get past the router was when my daughter was visiting a site I suspect ...

QChain saved me a bunch of rebooting time, even after belatedly installing SP2 to cut the number of claimed needed hotfixes. Although none of the remaining 8 hotfix articles seemed to apply to my case, I installed them anyway and a script with QChain worked like a charm.

OK, I've now got a clue. A helpful person on the Netscape usegroup suggested deleting the inbox.snm file, and it worked.

I have no clue what this file does or how its corruption can cause this problem.
