hi all,
I have a problem in phase2 when I trying SSG550M (screenos 6.2) as hub and srx100 (junos12.1) as spokes. The message is there was preexisting session from the same peer. Spokes (SRX100H2) are behind the NAT devices with dyanmic IP. The first two tunnels (one spoke ssg5 and the other srx100) come up but third tunnel with third spokes srx100 P1 come up but P2 fail. I also change soft life time buffer time in ssg side but the same error. How can I solve it?
