Have a problem with fragmented packets trough different ASA55xx boxes.
My ISP have tested the infrastucture and packets up to 1500B are delivered to my outside interfaces, but trough the ASA's i can only get packets up to 992B (ICMP) and when i try packets above 1380 i get reply that DF should be set???
traffic to the inside interface is replyed on 1500B packets.
I have no idea why sizxe is decreased so much trough the ASA's but it do influence on the the users experience on my WAN locations.
