PIX dynamic NAT issue

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
