[Openswan Users] VPN connects then disconnects after a minuite

[Brad Chang]

Hi everyone,  Basically my vpn will connect and everything looks good.  but I  
cannot ping anything on the other side but I do see the ESP packets comming 
into the interface.  I have an open firewall rules at this point so its accept 
all.  basically I can get it to verify password and register the computer and 
give my vpn client an ip address but then after a minuite the connection will 
tear down.. below are some logs of this .. thanks for any help . (after the 
first connect the vpn server no longer replies back to my client .. I have to 
restart ipsec to make it let me connect again) but then it just hangs 
on "verifying username and password
