Dear All,

Please can I ask how to set the MTU and MSS for WAN2 (PPPoE) in Drayek 2820n.

The command "wan ppp_mss xxxx" does not work in 2820 it seems.
I did "wan mtu xxxx" and "wan mtu2 xxxx", then do restart.
When I test with Linux ping-s xxxx IP the Draytek changes have no effect.
Must be me??

When making MTU and MSS changes in some other firewalls I own changes are reflected immediately.

Your help will be much appreciated.

Best regards,

I have the same issues so it is not you !!!

There is a similar issue with a 2850 here

My 2830 works fine via telnet and W 7 & W 8, thank God because there is not option via UI ... is not possible to set it manually via the UI? WAN >> Internet Access? sometimes the telnet has bugs with few firmwares
