Incoming NAT on Multi Wan setup Fails
Incoming NAT on Multi Wan setup Fails if client is coming from one of the WAN subnets
Scenario (bogus IPs)
Wan1 : Static IP 10.1.1.1 / 24
Wan2: Static IP 172.16.1.1/24
192.168.1.10 WWW server
192.168.1.15 www server
LoadBalnacer1 Wan1 and Wan2 Failover only outgoing only.
Port forward Nat. 10.1.1.11 -> 192.168.1.10 port 80
Port forward Nat. 172.16.1.1 -> 192.168.1.15 port 80
Outside Client. 10.1.1.100 can access 10.1.1.1 can ping 172.16.1.11 but cannot pull up web page on 172.16.1.1
Outside Client. 172.16.1.25 can access 172.16.1.1 can ping 10.1.1.100 but cannot pull up web page on 10.1.1.100
Any other outside client as long you are not on one of the networks work as expected.
Can you tell me If this a setup issue? Any ideas how to fix?
10.1.1.100 doesn't know where to find 172.16.1.1 unless
a)10.1.1.1 is its default gateway or
b)it has a static route designating 10.1.1.1 as the gateway to 172.16.1.1/(24-32)
If 10.1.1.100 can ping 172.16.1.1 then perhaps you have done one of the above?
