Two Way NAT + PPPoE

is it possible to do two way NAT through an ADSL connection (let's say using PPPoE)? if there are any links to products/configs, it would be great.

Re: Two Way NAT + PPPoE

PPPoE and NAT are compatible.

I'm not sure what do you mean "two-way NAT"?

If you mean PAT, it is one thing,

if you mean two way dinamic NAT it is different.

For practical purposes, consider the PPPoE only as a protocol

for obtaining the IP address. As soon as TCP/IP stack is in place,

all ports ot TCP are supposedely open, so you should not have NAT problems.

I'd suggest to refer to CCO with PAT/NAT keywords.

Best,

Plamen
