I have checked the network configuration and it is as follows.
Trusted interface is 10.10.10.7/24
There is nothing in the blocked Sites
as for the network setting all of our servers are assigned an Ip address
which is 10.10.10.x with a subnet of 255.255.255.0 the DNS server is
10.10.10.1 so all servers point to it as the Primary. I also just created a
Seondary DNS it is 10.10.10.2
As for the AnyPPTP rule it looks like this
Incoming Enabled and allowed
From - PPTP_Users
To - External
Outgoing Enabled and allowed
From - External
To - PPTP_Users
I have connected via a VPN from outside of our network and everytime I
connect I can ony ping 1 or 2 servers. I am unable to ping our main server
which has the loggins and exchange however I just mapped to our applications
server and copied files from my computer to it.
What I find really strange is that sometimes I can ping and connect to one
server but the next time I can not. I am beging to get frustrated.
