Another technician and myself are scratching our heads over an issue at one of our remote school sites. We have blocked access to the 189.0 network so they cannot access the web or the rest of the WAN and only access local servers. The 199.0 network is open so they can access anything on the WAN. The problem we are having is WE cannot remote access the 189.0 network from our main school office (Via RDP or Dameware) although we can access the servers which are under 10.100.189.248 /0.0.0.7. We can only ping the rest of the addresses on the 189.0 network. Can someone please look over this ACL list attached and see what we are missing? Do we have to have an IN and OUT ACL or can we just leave the OUT ACL without an IN?
The 181.0 subnet is the WAN connection back to our office.
