Hi,
I'm trying to NAT out to two DSL modems.
I have three network cards on three subnets:
re0: 192.168.4.0/24 =A0 =A0 =A0 =A0 Internal
re1: 41.134.100.222/29 =A0 =A0DSL_A
re2: 10.10.10.5/24 =A0 =A0 =A0 =A0 =A0 DSL_B
I can NAT out to either re1 or re2, but I have to make my default
gateway point to the relevant gateway on that network.
How can I tell the route tables or the nat-to command what the gatewa=
y
machine is?
So I can do this, but ***only if my default gateway is
41.134.100.217*** (which is the gateway for that net):
pass out on re1 proto tcp from 192.168.4.0/24 to any nat-to re1
Likewise, I can do this, but once again, ***only if my default gatewa=
y
is 10.10.10.1*** (which is the gateway for that net):
pass out on re2 proto tcp from 192.168.4.0/24 to any nat-to re2
I believe I should be able to make this work without ANY default
gateway. But then where do I tell the system
what these two gateway machines are?
You need *A* default gateway, but it doesn't matter which you choose.
Then use route-to {41.134.100.217@re1, 10.10.10.1@re2} to redirect
traffic and nat-to rules for outbound traffic on the relevant interface=
s.
You also need similar tricks with reply-to if you want to accept
incoming traffic and make sure replies go out the correct interface.
I have the same problem, but my one of my internet connection has
static ip and gateway, the other has dynamic ip, this solution work
for me too?
Thanks, Elerdin.
