Hello list. I can successfully connect to my opensbsd 5.5. isakmpd / npppd IPSEC L2TP vpn setup. But (not knowing too much about netwoking) i think i'm having a mtu problem. I can do low volume traffic fine, but transmitting larger files stalls. I've tried as per suggested by others around the web the following. Added scrub on enc0 with an max mss of the pppx0 mtu. Tried with and without tcp-mss-adjust set to yes in npppd.conf.
Does anyone have a working configuration of this setup, my client is strongswan/xl2tpd on GNU/Linux debian 7.
