Hello List,

we do have a problem with VPN and three Sidewinder. Attached you can find
an ASCII graphic for our scenario. The problem is, when we make a VPN between
LAN A (Sidewinder A) and LAN B (Sidewinder B) everything is okay, that
means normal working, but when we want to work in LAN C (over Sidewinder C)
we got a complete "slow down"  on the session to LAN C and on the solaris
systems in LAN C. We do have this behave in two customer scenarios. At the
second  customer there is no Cluster/Fail-over Sidewinder (Sidewinder C), but
same "slow down" behavior.

Does anybody know a solution on that?

Best regards...

Olaf Otahal
