Probably a simple question, but I haven't been able to find anything in the
PPTP-guide or on the lists.
m0n0wall has two inside NICs: LAN for server/wired clients and DMZ for
For security reasons access from DMZ to LAN is restricted to PPTP - this is
WAN access through the PPTP is a another issue however :o(
The routing is fine - the problem is MTU related.
WAN is routed Ethernet with MTU 1500 - but PPTP is PPP with MTU 1396.
I have set m0n0wall to log anything coming through PPTP-interface, and I can
see that 1400byte-packets are coming in on the PPTP-interface from the web
servers I try to access.
m0n0wall sends an "icmp unreach/needfrag" back - to no avail.
Does anyone know a way around this?
...IPSec is probably better, but PPTP was SO easy to setup on win2003 ;o)
