I am trying to set up a IP Sec Tunnel between a D-Link DFL 210 and a D-Link DFL 800. Authenticating with Pre-shared key. But the tunnel wont go up running. In the log I find this:
12:52:33 Warning IPSEC
rev=1 local_ip=x.x.x.x remote_ip=y.y.y.y cookies=3f103e47ad0ff36bbcc4c2344fcd8bf9 reason="Invalid payload type in encrypted payload chain, possibly because of differ
I have a very similiar configuration running fine from another office. Only difference is that it's a slightly older DFL 210 and this problematic one is behind a Lan.
First question : what does this error message mean more exactly? Next : can someone guide me to correct my settings?
