We are facing two problems need help badly. I am giving both the problems here.
ISA Server 2006 at two locations (Location1and location2) as firewall and proxy.
location1 ISA has 2 NICs (Public and Private)
location2 ISA has 3 NICs (DMZ, Private, Public NAT)
Only Nated interface has the gateway configured
Problem 1
· From DMZ we cannot ping / telnet or send mail to external
· The same time its allowing both these from internal network
· From ISA Server we can tracert the external servers but we are not able to telnet to them on port 25
· If we monitor no denies are coming in the log.
Problem 2
· Site to Site VPN is not connecting between these two isa servers.
· We tried both preshared key and certificate options and also tried pptp
· When we configure preshared key the error is security negotiation timed out after 64 seconds
· When we configure Certificate its giving error no certificate found. No idea where to configure the certificates. All what we have done is requested and installed an administrator certificate as per the kb article on both the isa servers under trusted certificates
· Also we have added the root ca under trusted cas
We are getting an error Event id: 20111 from remoteaccess source
