Hello all!
I have one device Viola GPRS Gateway (violasystems.com) and Mikrotik router.
Mikrotik has static public IP address, Viola tries to connect it using L2TP protocol, but it can’t.
I get errors on Viola:

I know there are Viola’s errors, but maybe somebody can comment these errors because they are concerned with L2TP protocol?
In Google I didn’t find any topic concerned with these errors, only source files of L2TP Daemon (http://mia.ece.uic.edu/cgi-bin/lxr/http/source/avp.c?v=l2tpd-0.69).
Any suggestions?
Thaks!
