I have a problem with MTU size (I got ICMP fragmentation needed from router, required MTU size is 1545bytes).
ok, I did some packet traces and configuration changes:
I tried change MTU size on ACE interfaces (routed mode) - without success, MTU size in packet trace was without change.
I tried change MSS on ace ifaces, because mss size between server and ace is too high (segment size 1460bytes). ok, it works (syn/syn-ack/ack phase)! but packet trace shows, that size of segments(and packets) is without change. I got always ICMP fragmentation needed.
ok, last chance is clear don't fragmetn bit in the packet ('ip df clear'). it works and communication between server and client is successful!
it may seem, that problem is solved. it is, but it works only with disabled normalization ('no normalization') and it's not acceptable.
my question is:
where can I search a problem?
with normalization enabled, packet trace on server side shows only syn/syn-ack/ack and fin/... in the same time. client side shows only client's packets, no packets from ace module.
