Port forwarding with dual isp failover?

Hello, I've configured failover with dual isps, but have not yet got port forwarding working. 

I'm trying to forward packets coming in on g0/0 from the primary isp to corresponding servers on my network.

Port forwarding with dual isp failover?

Hi,

ip nat inside source static tcp 10.1.10.23 80 75.149.249.73 2031 extendable

ip nat inside source static tcp 10.1.10.24 80 75.149.249.73 2032 extendable

You're using same ISP for both static PAT entries, if you want to use secondary ISP for second one you should do this:

no ip nat inside source static tcp 10.1.10.24 80 75.149.249.73 2032 extendable
ip nat inside source static tcp 10.1.10.24 80 192.168.1.254 2032 extendable
And in this case you don't even need extendable keyword as you are using different outside and inside IPs.

Regards

Alain

Port forwarding with dual isp failover?

Correct i'm not to worried on the failover for these as they aren't critical(and the t-1 doesn't have enought bandwidth to support them) so i just want to get them on the 10.1.10.0 network.   Other than that it looks good?
