pppoe / masquerade / surfing secure sites

Having a hard time tracking this one down… Subscribers use RB112 with wireless card to connect via pppoe. src-nat=masquerade is on for the connection. Issue is at secure web sites - initial https page displays properly, but after entering logon info, page hangs and times out . Take the same MT and change it to static IP, no pppoe, srcnat=src-nat and all is fine.

Thanks

change the MTU

Wow! I had to bring MTU all the way down to 1388!

The MSS mangle rule mentioned in other posts didn’t work either.

Oh well, works now!

Thanks
