You need to check out the VPN Masquerade HOWTO at
http://www.linuxdoc.org/HOWTO/VPN-Masquerade-HOWTO.html written by John
Hardin (BTW John, this was a great resource for getting my VPN up and
running). I got rid of my stock RH6.0 2.2.5-xx kernel and downloaded the
2.2.12 source (current at the time). I then patched the kernel source with
John's IP_Masq_VPN patch for the 2.2.12 kernel
(ftp://ftp.rubyriver.com/pub/jhardin/masquerade/ip_masq_vpn-2.2.11.patch.gz)
and recompiled with all the firewalling and masq'ing options set.
After you've installed the new kernel you need to portfw your tcp/1723
requests to your internal NT pptp server using the ipmasqadm tool.
# /usr/sbin/ipmasqadm portfw -a -P tcp -L <EXT.VIRTUAL.INT> 1723 -R
<INT.PPTP.SERVER> 1723
After this is setup you need to start the ipfwd arbitrary protocol
forwarding tool to redirect protocol 47 to your NT pptp server
(http://www.pdos.lcs.mit.edu/~cananian/Projects/IPfwd/).
# /usr/local/sbin/ipfwd --masq <INT.PPTP.SERVER> 47 &
That's it. PPTP requests come in on tcp/1723 the initial handshake is
completed and the tunnel gets established using Protocol 47.
