Demand Dial Routing

Hi,

I am having some problems getting demand dial routing to work in one of my branch offices, i believe the problem is to do with the firewall blocking the traffic.

Could anybody please tell me the Ports and TCp/UDP e.t.c. that a demand dial routing connection uses (VPN demand dial routing)?

Thanks,

Chris.

AFAIK, you only need to allow the standard PPTP [port 1723 and protocol 47 (GRE)] to pass through.

In case you haven't seen it, Microsoft has a pretty good troubleshooting page Here and you might get useful info from the Technet chat Here.
