[pptp-server] Re: Troubles with GRE masquerading

[Anthony Foiani]

Hi again.  I experimented a little more today, and I *think* i've
gotten a bit farther.  I removed the gre MASQ entries from my
"forward" ipchain, and use "ipfwd" to forward+masq the GRE traffic.  I 
invoked it on the firewall box like so:

   ipfwd --syslog --debug --masq 192.168.1.11 47 &

where 192.168.1.11 is the internal pptp server (running pptpd).  I saw 
it transfer various bits of traffic back and forth, but the pppd
process still died with the GRE or PTE error -1.

Thanks for listening,
Tony
