We have an internet connection from 2 different ISP, I want to use the same PIX 525 firewall 7.0(6)
I would think this is possibly a routing issue. route outside 0.0.0.0 0.0.0.0 212.12.181.145 1 I can see you have NAT’d both interfaces using the relevant IP blocks from your providers, however you are routing all traffic to provider IP 212.12.181.145. This provider may be dropping the traffic from the 78.93.12.197 as possible IP spoofing. [...]

The Domain Name System (DNS) associates various information with domain names; most importantly, it serves as the “phone book” for the Internet by translating human-readable computer hostnames, e.g. www.example.com, into IP addresses, e.g. 208.77.188.166, which networking equipment needs to deliver information.
