Unable to access remote access VPN L2TP Client from main office

Hi shahzaib,

Please check and verify traffic flow under MONITOR & ANALYZE || Diagnostics || Packet Capture passing from the same firewall rules and drop packet

Regards

Hi shahzaib , what is the use-case you are trying out by pinging the virtual ip assigned to the L2TP client? 

You should be able to ping virtual ip assigned to the L2TP client from SFOS or from the LAN client of SFOS (as per your diagram).

Do you have Firewall rule enabled to accept LAN to VPN for the hosts of interest? if not, this is required.

Do this while pinging virtual ip assigned to the L2TP client either from SFOS or from LAN client of SFOS

tcpdump -n host <l2tp ip> and icmp

In working case, you should be seeing packets egressing from ppp0 interface and ingressing back.
