1:
I have two servers with two Real ip address 212.xxx.xxx.xxx and
203.xxx.xxx.xxx (both also connected via LAN 192.168.xxx.xxx)
Server One is Internet connected via dial-up modem and Server Two via
cable modem.
Can server on 212.xxx.xxx.xxx (modem connected) be configured to route
its web-server output thru the LAN via 203.xxx.xxx.xxx (cable modem)
route to the Internet using ipfwadm alone (or ipchains). The point being
that the modem machine has a fixed ip address while the cable machine,
only leased. (and I need to keep the fixed)
2:
Can port forwading be made to work across this type of setup if (for
example) the machines were not connected via the LAN

For these kinda questions it is usable to make some ASCII art that
visualises all the hardware with the ip addresses. If you send it then
I can answer your question.

There appears to be a number of solutions possible that allows me to
modify my original designs for the below construstion. Situation should
firm soon and I'll repost with clearer detail at that time.

Hope your around to answer ...

1. Routing thru Subintefaces

I have a Solaris 7 box in which I would like a certain route to use a
subinterface as opposed to the main pysical interface.

A few lines from a netstat -rn:
10.240.252.0         10.240.252.23         U        6   2467  qfe1
10.240.252.0         10.240.252.53         U        6      0  qfe1:1
10.240.252.0         10.240.252.54         U        6      0  qfe1:2
10.240.252.64        10.240.252.62         UG       0   3904
10.240.252.128       10.240.252.62         UG       0   1131

I need to route to 205.174.35.1 via the 10.240.252.62 gateway. This is
normally not an issue, just do a:
route add 205.174.35.1 10.240.252.62

However the requests to 205.174.35.1 must originate from 10.240.252.53
(qfe1:1) due to the firewall configuration. We also need the .23
address to route other packets so switching the ips is not an option.

Is it possible to configure Solaris to route to 205.174.35.1 via qfe1:1
and if so how?

Thanks,
Brian
