This may or may not be related to my problem with passing ipsec verify.
I have configured L2TP/IPsec VPN on Ubuntu 13.04 following Ubuntu's community documentation and while IPsec connection seems to be established correctly, connection to xl2tpd fails. Here's a log from the client
Aug 25 14:07:10.058 004 "connection-name" #2: STATE_QUICK_I2: sent QI2, IPsec SA established transport mode {ESP=>0x542d1443 <0x2e94cf9a xfrm=AES_128-HMAC_SHA1 NATOA=none NATD=none DPD=none}
Aug 25 14:07:11.060 xl2tpd[31068]: Connecting to host my.server's.ip, port 1701
Aug 25 14:07:16.065 xl2tpd[31068]: Maximum retries exceeded for tunnel 6146. Closing.
Syslog on the server shows nothing at all. Even with
debug network
debug tunnel
in the configuration. It's as if the connection to xl2tpd is never made.
What's going on? Could it be a firewall issue? I have tried flushing all my rules and more permissive configurations to no avail. Or is it some problem with forwarding as indicated by ipsec verify?
Or at least, how can I get more information?
