As u have tested you are able to connect but not able to reach anywhere, though from internal network I can ping your vpn IP 172.28.31.129.

In VPN session i can see sometimes bytes send and receive, and sometime only sending no recving.

No firewall involoved in the path between the concentrator and desired server 172.28.31.171.

Both connected on same switch but different VLAN. but Inter VLAN routing is working and both are able to ping.

ONly remote access client 172.28.31.128/248 is not able to reach anywhere.

VPN concentrator has public default filter on public interface and private filter on local interface.

Concentrator version is 4.7
