WebI have a number of VPN sites where the MTU is lower than standard (1500). I have had at least one site where fragmentation of packets has had an effect on the success of building an IPSEC tunnel. I am able to set the MTU on the equipment at the remote sites. However, at head office I wouldn't want to set the MTU to the lowest common denominator. WebFor traffic exceeding the outbound interface MTU after IPSec overhead is added there are several "fixes" PIX/ASA side. Change the MTU on the PIX/ASA to a lower number (1380 is common) forcing sending stations to react -- not always in the desired manner. Change the MSS (TCP only, not useful for UDP) Let the PIX/ASA Fragment.
