udp packet problem

[Tyrone at telecity.se]

Hi,

 

This problem goes away if I turn traffic shaping off.

 

My configuration file looks like this:

 

ipfw pipe 6 config bw 65000Kbit/s #setup shaping pipes 65Mbit

ipfw queue  11 config pipe 6 weight 100 

ipfw queue  12 config pipe 6 weight 100 

ipfw add 112 queue 11 ip from any to any in via vlan13 

ipfw add 112 queue 12 ip from any to any out via vlan13

 

Why can't I have traffic shaping on without affecting the customers
service they want to be able to send udp packets larger than 2k?

We have a Freebsd 5.4 router doing traffic shaping on a vlan interface.

 

Problem is we can't receive UDP packets larger than 2K is this a
limitation or a setting within IPFW?

 

How can I fragment UDP packets that are larger than the interface MTU ?
kernel option or FW ruleset ?

 

regards
