Hi,

does anybody use ppp(8) over TCP (as described in man) for IP tunneling? I had
Lotus Notes server with WWW server on NT and FreeBSD box which provides IP
tunnel. It seems that only relatively small TCP packets carried across tunnel:
e.g., HTML page are loaded without images. With "telnet 80" I found that for
images only HTTP header is delivered, without body. Locally (without tunnel)
the WWW server works as expected, so I believe the cause is in tunnel. Setting
MTU to the values from 2000 to 300 did not solve the problem. Can anybody help?

PS. FreeBSD-3.2-RELEASE on the one hand, 
    route add -net a.b.c.d -netmask 255.255.255.252 10.0.4.2 
    FreeBSD 3.0-RELEASE on the other, ipfw add fwd 10.0.4.1 ip from a.b.c.d/30

Sergey.
