Why couldn't I access peer router's Web UI through LAN-to-LAN VPN?
Sometimes we'll find that we couldn't access peer router's Web UI after LAN-to-LAN VPN connection established successfully between Vigor Routers, while both ping and telnet to the peer router work normally, and accessing other websites also work.
You may follow the steps below to lower the VPN MSS (maximum segment size) value to meet some ISP requirement:
- Telnet into the router then type “vpn mss ?” command to check the usage of vpn mss command.
- Type vpn mss set [connection type] [mss value] to modify mss to a lower value.
