Cisco RV345 PPPoE padding problem

[vladimirk7]

Hello, my ISP adds a padding bytes to a TCP packets encapsulated via PPPoE, for some unknown reason, SYN and PUSH packets are received fine by the RV345 router, but FIN packets are dropped, that leaves TCP connections that closed by remote host opened. This causes a very serious problems with browsing, gaming etc. Please help.

Thanks

Hi

So why dont you reduce the MTU of the wan1/wan2 interface on which the pppoe-wan is configured? Please see the attached screenshot. Iam thinking that this should compensate for the padding that is added further down the link/route
