I’m setting up a pix 501 and am having an issue gaining access to the outside. From the pix I can ping the Internet and the inside network. From the inside network I can ping the the inside interface of the pix, but not the outside interface or the Internet.
I configured PAT and can see my connections:
pix(config)# show xlate
9 in use, 18 most used
PAT Global 192.168.141.71(1082) Local 192.168.182.100(3333)
PAT Global 192.168.141.71(1081) Local 192.168.182.100(3331) …etc
The 192.168.141.0 network is outside facing, while the 192.168.182.0 is the inside network.
My understanding is that all I need for PAT is this:
global (outside) 1 interface
nat (inside) 1 0.0.0.0 0.0.0.0 0 0
What bothers me more than anything is the fact that I can not ping the outside interface (192.168.141.71) from the inside.
The pix is handing out DHCP and I get an IP of 192.168.182.100/24, DG:192.168.182.1, DNS: 4.2.2.2.
