Hi friends,

I'm working for a small ISP. We are configuring PAT on our CISCO PIX-525 [SW-Version 7.2(2)] to map private ip addresses to public one IP. The problem is that most of our user can't give to someone their webcam while using the yahoo messenger and can't add new contact in yahoo messenger.

 The error msg pops ip while users attempt to broadcast their

webcam and add new contacts. That msgs seems like "The server is busy now. Please close the window or a few minuts later" or "Your request to add a contact has taken longer than expected to complete. The operation might have succeeded. Please check your messenger list later".

I used static nat on one test user. And then added new contact

to yahoo messenger. All attempts success in this case. Also webcam was working fine.

So, when it works with static NAT through same PIX what is the problem with PAT?

How i solve this problems?

If anyone can point me to some configuratios or provide some assistance that would be great.

Thank you,
