Hi. I have a site to site VPN set up to connect two offices. Each office has a server running RRAS which is connected between two hardware routers. One router connects to the internet and passes all traffic to the RRAS server as DMZ. The other router connects to all the back office computers. The first site, the original one, works with no problems. But on the second site (our West site) we have a problem of severe delays when accessign anything external to the LAN. These delays are random and often several seconds in duration. The delays are there whether we are accessing the other site, or when accessing an internet site.
I have found out that stopping the RRAS service will eliminate the delays when connecting to internet sites. Also, if I am on the RRAS server I can change the routing table to make external connections run at full speed, but when I do this I lose connections to the local subnet. I am no network expert but I can usually get thing to work - but this has me stumped for weeks now.
Our Lan configuration is:
East Site: External Router 192.168.0.1, Internal Router 90.0.0.1
West Site: External Router 192.168.1.1, Internal Router 90.0.1.1
Here is the routing table on the RRAS server:

Persistent Routes:

0.0.0.0 0.0.0.0 192.168.1.1 Default
I should mention that the RRAS server is running Windows Server 2008, Standard Edition (32 bit). If I delete the 90.0.1.0 route then connections to various internet sites run at normal speed, but then there is no connection from that RRAS server to the local subnet (90.0.1.0 LAN).
Hope someone can give me a clue here.
Thank you, Russ
