My IPSEC VPN tunnel between two pix's has gone down and after trying
the normal reboots I attached a syslog to one end and got a ipsec
isakmp phase 1 retransmit message
cisco doesnt really explain the causes of this.
Does anyone have any ideas what this means ? or the causes ?
I have attached both configs
That is not good - you need to do the below:-
1) Check your config
2) Check your config
I say it twice as about 99% of network related issues are configuration based.
