PPTP to vpn provider - cant get to secure webpages

Hi there,
I’ve setup a PPTP account but when I try to access secure webpages, the router doesn’t seem to respond. I.e. if I goto Paypal.com - it never loads.

If I bypass the MK router and use my laptop to directly connect to the VPN server, all pages load fine.

Any idea what could cause this?

Hi Fewi,

I’ve tried to add that rule to the setup (even put the MTU to 1380) but I’m still unable to get access to the secure pages.

Any other suggestions?

Firewall or NAT rules are blocking the other traffic, would be my next guess

I managed to get this working. It kinder helps to set the value on the actually pptp interface aswell!
