Question : UDP/RTP packet size

Hi,

I am currently trying to write an application to send/receive video using rtp packet.
the problem is when i tested it, i dicovered that my packets were blocked by my firewall, which nitified me by this message:

Denial of Service "Jolt2 Attack" attack detected.
Description:
 Jolt2 attacker floods illegally fragmented ICMP or UDP packets into your computer and causes your CPU utilization to be 100%

of course i could remove my firewall, but i would prefer to make my application generating "legally fragmented" packets...
I have no idea which size they should be (or not be), so i hope someone here knows;-)

regards,
Raph

Answer : UDP/RTP packet size

Some firewall intrusion detection system is configured to not allow fragmented tcp packets. make your application to not send fragmented packets. As I know (not sure about this one, however - I'm basing on some logic ... :)) if you have a small MTU then your packets may being fragemented so they could be sucessfully transmited. Try to use a larger mtu. I wont post a link about how to set the mtu cause I'm not realy sure about this could be your problem.

Cheers.
