Anyconnect connection: VPN connection is fine. Reaching a specific network is not accessible.

[Supercell292929]

Hello,

    I'm curious as to why I can reach our 10.0.0.0/8 network from the AnyConnect VPN pool 192.168.200.100-.200, but not our 172.16.250.0/24 network. The setup is identical on our 5555-X. Do I need a "route-lookup" statement on the (NO DICE) nat? (seen below) 172.16.250.0/24 is statically routed on our ASA.:

object network obj-192.168.200.0

Hello,

try to configure your split tunnel ACL like this:

access-list VPNIT_splitTunnelAcl standard permit any4

What does your group policy look like ? Can you post the full config ?

[Supercell292929]

I removed the 3 ACL's seen below and replaced them with what you recommended: "access-list VPNIT_splitTunnelAcl standard permit any4." No sooner did I do this then my home connection to the internet dropped (the AnyConnect tunnel stayed up. I just couldn't get out to the internet from my PC [DNS servers were no where to be found]). I could not get to 172.16.250.0/24, but could still get to the only switch I could always get to: 10.20.6.1/24 via AnyConnect.

VPN-REMOTE (THE ONE I USE):

ip local pool VPN-remote 192.168.200.100-192.168.200.200 mask 255.255.255.0

#####

access-list VPNIT_splitTunnelAcl standard permit 172.16.250.0 255.255.255.0

ADDING THESE THREE ACL'S (ABOVE) BACK AFTER REPLACING THEM WITH THE ACL YOU SUGGESTED BROUGHT MY HOME INTERNET BACK UP IMMEDIATELY.

ssh to a switch on our 172.16.250.0/24 = cannot connect and NO hit count (below). This is also what occurred when replacing these ACL's with the one you recommended (ASA(config)# no access-list VPNIT_splitTunnelAcl standard permit any4)

Hello,

sorry for the misunderstanding, I thought your split tunnel access list contained just the one line you originally posted.

Either way, make sure you have the below configured:

access-list VPNIT_splitTunnelAcl standard permit 10.0.0.0 255.0.0.0
access-list VPNIT_splitTunnelAcl standard permit 172.16.0.0 255.255.0.0

Thank you for your suggestions, however, it still does not work. Here is the entire layout of the AnyConnect VPN:

I have a feeling it has something to do with this:
