Hi All,
Last Saterday I've upgraded our VPN endpoint router.. Everything looks fine and all Tunnels were up and running. Now we explore some problems with several applications through a tunnel. The problem looks to be related with the MTU size; after setting the MTU site on the clients to 1400 all applications are working fine. I've made no changes to the configuration of the router.
Old IOS: c3640-jk9s-mz.122-23 New IOS: c3640-ik9s-mz.123-14.T7 Remote Site = Checkpoint NGX R60A on Crossbeam platform
Has somebody experienced similary problems ? Is there another solution (then changing the MTU on the clients) ? What is changed int the IOS from 12.2 to12.3 regarding IPSEc tunneling and MTU sizes?
Thanks,
Tom Lauwereins
