I have an ADSL modem and my access provider requires that I connect to
the modem using PPTP. I can use a Linux firewall to connect to the modem.
The public IP address on the firewall is the address of the tunnel. There
is no point in letting Snort snif between the modem and the firewall,
because of the encryption.<br><br>
I could snif behind the firewall, but then I would see only see the
traffic from and to internal hosts and not the traffic that is stopped by
For educational purposes I would like to see *all traffic*. Is it
possible to install Snort on the firewall and snif the virtual VPN
Alternatively, does anyone know of an ADSL router that will forward *all*
traffic it receives on it's public IP address to an inside IP address?
Just setting port address translation for a few ports won't do.<br><br>
I really only have one public IP address. <br><br>
Thanks in Advance,<br>
