Also, do the tunnels successfully do path MTU discovery? WebLet the PIX/ASA Fragment. In the event that df-bit is set in the inner IP header and fragmentation is required to fit through an IPSec tunnel, permitting the PIX/ASA to clear the df-bit is also an option. Note that clearing the df-bit requires PIX/ASA OS 7.0 and greater. The "venerable" PIX 6.3 (5) will not cut it.
