What ipchains rules do I need to add to masquerade incoming pptp connections from a gateway (e-smith 4.1.2) to a private internal server (SME 5.0)?
I don't need to maintain pptp connectivity on the gateway, so i think i can just forward port 1723 on the gateway to port 1723 on the internal server.
Apparently SME 5 has problems with PPTP in server only mode and i've applied the recommended fix from the e-smith.org site.
Do I need to use ipfwd to make sure the GRE protocol is passed through? if so how do I set this up?
Any help would be muchly appreciated.
