IPSEC won't establish with NAT traversal asg v7 to v8.2

I upgraded our hub firewall terminating 34 tunnels initiated from v7.509 asg's, and only had 30 of 34 tunnels establish. I noticed the 4 that wouldn't establish were using nat traversal across another router(FIOS router or Linksys WRT54g). No matter what I tried, I couldn't get the tunnel to establish. These tunnels were esstablished on 8.103 prior to the v8.2 upgrade. I reverted back to 8.103 to resolve the issue.

  • The ISO on the website is 8.103, and my pre-8.200-upgrade backup was available on the ASG, so I downloaded both and reverted back to 8.103. As soon as the config was restored (and DNS got updated!), I was able to use L2TP just the way I'd become accustomed.
