IPSEC VPN between 506e and 501

Hi all,

Im having trouble with a site to site ipsec vpn connection.

Yesterday I had to change over to a new internet connection, so I swapped out the router and changed to a new set of ip address at one side of the connection but now I cannot reestablish connection.

it appears IKE is coming up, I think it is the router but ive disabled its firewall so not sure what else it could be. its a nortel BSR 252 if that helps

heres some of the syslog -
