The smoke clears! Thanks, that helps a lot. :-)

Agreed, that will work.
Like I mentioned, though, if you can turn off DHCP at the WRT54G
location then everything can be made automatic. The laptop would
request an IP address from the WRT160 and would always get the same
one because that router knows how to reserve the address, but at the
WRT54G location the laptop wouldn't be able to get an IP address via
DHCP (because you'd have DHCP turned off) so it would use the static
IP address you've told it to use. Free, easy, and automatic, but it
requires that you turn off DHCP at the WRT54G location, which may
cause other issues of you have multiple DHCP-enabled computers at that
location. Microsoft calls this "Alternate Configuration".

The options, in no particular order:
1. Manually forward port 5900 to the laptop's IP when you go to the
vacation home, as you're doing now.
2. Upgrade the WRT54G to another WRT160, if you otherwise like your
other router, then reserve an IP address and permanently forward port
5900 to that IP.
3. Use Microsoft's Alternate Configuration feature.
4. Use one of many free 'net switcher' tools to assign your preferred
IP address to the laptop at the WRT54G location. Permanently forward
port 5900 to that IP in the router.
Did I miss anything?
