Hello,

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

Any idea's?

You can only have one effective gateway.

If you need two DSL connections, I would suggest getting a multi-wan router that can do a basic load balancing (basically, it chooses a connection for each session so the session always stays on the correct connection).

if you have 2 gateway then one packet goes from first one and another from the second one
it causes jitter
you should have 1 gateway

is there any linux based router/firewalls that with two nic's can act as a loadbalancer and allow this to work?

alireza1023,

I'm am amazed at your extensive and highly inaccurate answer to Aucklandit's last question. Especially considering that many routers are based on *nix operating systems.


Among the possibilities:

Now, that said, this is extremely unwise considering you could get a router for a few hundred dollars and save yourself some time and hassle.

yes
but I studied about that and found that none of oses can handle multi gateway
you should handle it with routing protocols
