Hey guys,
I decided I should make sure I can properly configure the remote access
vpn in its current state before I try to modify it for my uses.
Unfortunately, I cannot seem to get it to work using the instructions on
the website. I activated the VPN from the web UI and added a user
account. These steps succeeded and I am not seeing any errors in the
management or agent logs. I configured the VPN client (Mac OSX) but when
I connect it errors saying "L2TP-VPN server did not respond." If I
enable ICMP in the firewall I can ping the IP associated with the router
from the client machine.
If I console into the VRouter and run lsof -i I can see that x2ltpd is
listening on l2f (1701).
I have tried running nc -u VROUTERIP 1701 from the client to manually
test if the router is listening on port 1701 but the command never
finishes. I thought this was odd because I expect that if x2ltpd was not
listening on 1701 that nc would fail. The way it blocks reminds me of a
firewall drop. But the firewall configuration for the VROUTERIP is
showing 1701, 4500, and 500 UDP allowed from 0.0.0.0/0 both in the web
UI and via iptables -L -n
Not sure this is relevant but I did notice that if I tail
/var/log/syslog on the VRouter there are the following lines close to
the bottom:

Any thoughts on this or ideas for how I can troubleshoot the issue?
