Hi, I have a PIX with the following config: 63.174.x.x OUTSIDE 172.16.1.x INSIDE 10.200.1.x DMZ My DNS servers are on the DMZ.. and also have an outside address static mapped. I have an alias command taking the OUTSIDE address and mapping it to it's address on the DMZ (for inside)... My problem is it seems like the xlate table is getting messed up.. because I'll set people up with: 172.16.1.6 (ip address) 172.16.1.1 (gateway) 10.200.1.2 (dns1) 10.200.1.25 (dns2) It will work fine for a while.. and then die... they can ping and go by IP but they can't do DNS resolution. If I change their DNS to the 63.174.x.x DNS server address (same machine) it will start working again... for a while.. and then die.. but if you switch back to the 10.200.1.x address it works fine. It also seems to start working again if I do a clear xlate. Any idea on this?
