Lower VPN MSS to access the peer router's Web UI through VPN

Sometimes we find that we couldn't access peer router's Web UI after LAN-to-LAN VPN connection established successfully between Vigor Routers. If ping/telnet to the peer router and access other websites work, you may follow the steps below to lower the VPN MSS (maximum segment size) value to meet the ISP's requirement.

  1. Telnet into the router  then type command vpn mss ? to check the usage of vpn mss command.
  2. Type vpn mss set [connection type] [mss value] to modify mss to a lower value.
