Hello!
I am having problems with my VPN clients getting access to the networks over a MPLS infrastruture. I can reach these resources form my Core network (172.17.1.0/24) and my Wifi (172.17.100.0/24) but not from my VPN network (172.17.200.0/24). From the VPN I can reach the Wifi network (which is behind a router) and the rule that allows that also allows access to the other networks but for some reason it is not working.
When I ping inside the core network from VPN I can connect and get responses. When I ping to the Wifi network, I can get responses and connect to resources there. A tracert to the wifi network shows it hitting the core switch (a 3750 stack) @ 172.17.1.1, then the Wifi router (172.17.1.3) and then the host. A tracert to a resource on the MPLS network from the VPN shows a single entry (the destination host) and then 29 time outs but will not ping that resource nor connect.
I've posted all the info I can think of below. Any help appreciated.
*** Here is a tracert from a core network machine to the resource we need on the MPLS:
C:\Windows\system32>tracert 10.2.0.125

Hi Roger,
I bet you already checked it, but does the MPLS end router has route to VPN client subnet 172.17.200.x (or default) pointing to core rtr)?
Also, if the MPLS link has any /30 subnet assigned, you may need to include that as well in Object group LAN-NETWORKS.
Thx
MS

I have asked that the route be added and have been rold it is.
Do I need to add each network to LAN-NETWORKS that is between me and the resource?
Thx for responding!
