I have a client who can not colocate, as to handel the load has two DSL connections to his windows server 2003 with two nics.
3389 is forwarded to the server by both dsl modems but he can only get on via one of the static dsl IP's.
the server has two nic's is it,
one being 192.168.1.248 with gateway of 192.168.1.254
two being 192.168.1.249 with gateway of 192.168.1.154
but on 255.255.255.0
can only get on via the public IP of 192.168.1.154 from external, can access .248 & .249 on local no problem.
modem 192.168.1.254 port forwards to .248
modem 192.168.1.214 port forwards to .249
