I have the dual Ethernet setup. The IOS is use is 12.0(15) IP/FW
Firewall>sho flash
System flash directory:
File Length Name/status
1 6261572 c2500-io-l.120-15.bin
[6261636 bytes used, 2126972 available, 8388608 total]
8192K bytes of processor board System flash (Read ONLY)
If you have only one global IP, then you are looking to configure NAT
Overload (which is the same thing as PAT).
