Hi,

I have trouble with my network being that I can't have 2 outgoing pptp
connections at anyone time (see below for info). It has been suggested that
I perform a LAN packet trace against the 2nd PPTP connection.

Im familiar with TRACERT via a command prompt but was not sure if this was
what is meant by LAN PACKET TRACE. I need to trace pptp packets - i didn't
think tracert would help i.e cant specify protocol.

Can someone please explain ?

Thanks
Scott

PPTP lan clients + servers
host

The lan clients are a mixture of 2000 and XP pro. When have about 50
external pptp services that we need to connect to now and again. When one
internal clinet connects to a remote pptp service the connection is fine
until another internal client connects to another remote pptp service - at
this stage the first clients connection drops.

Can anyone suggest where the problem may lie or suggest any troubleshooting
tips ?

(NOTE: i also host a pptp service but incoming connections are rare. I dont
think the incoming traffic is effected but im not 100% sure).

one other thing. it was also suggested that having
LAN>FIREWALL>FIREWALL>ROUTER>ISP may cause a problem because of all the NAT
forwarding. Surely this cant be a problem ? it is now how everyone works ?
