PIX dynamic NAT issue

benchdlosangeles — Fri, 21 Feb 2020 09:21:07 GMT

Hi,

I'm experiencing this problem with our PIX. When using dynamic NAT on the PIX our LAN with

private IPs cannot get to some sites, i.e. 3com.com But using a DSL connection and not behind the PIX it's not a problem with the same PC.

One solution

that works is create a one-to-one static NAT for my PC or use a proxy

server to surf the internet.

I've used stable versions of 6.x and 7.x and I can telnet to port 80 of the problem websites while behind the PIX but when I use the browser it'll get stuck with "Waiting for reply..."

Is this a known PIX problem with dynamic NAT? Any solution?

Thanks,

Benjamin
