Multiple internal subnets on asa 5510

Postby TazMan1 » Wed Jun 27, 2012 6:54 pm

Hello All,

I am implementing a 5510 to replace our old pix firewall that we have. I have a few 5505's installed throughout the network and don't have this issue with them. With the 5510 I have 2 internal subnets on my router. A 10.10.10.x and a 10.10.20.x. I can get anything on a 10.10.10.x to access the internet but anything with a 10.10.20.x can't. What am I missing here? I am using 2 interfaces on the asa, one outside and one inside and have the asa set to route anything with a 10.x.x.x to my router. I can ping 10.10.10.x things from the asa but not 10.10.20.x. Any thoughts would be greatly helpful.

Check your nat settings and make sure your NAT ACL includes both subnets.
