Re: PIX 501 static map to enable Yahoo message' webcam

Hi Jeremy,

Have you tried:

> access-list inside permit tcp host any eq 5100

> access-list inside permit ip any any

> access-list inside in interface inside

Makesure the client IP address is a static address if you have DHCP running on the inside. And also, after configuring the inside ACL save with cmd 'write memory' and do cmd 'clear xlate'. Now try and see if you can run the formentioned service (yahoo webcam) from your clients PC.

Hope this helps and let me know how you get on.

Re: PIX 501 static map to enable Yahoo message' webcam

Hi,

Thanks for your reply.

I have tried to add the followings.

access-list outside_in permit tcp any host 203.198.172.bbb eq 5100

access-list outside_in permit tcp any host 203.198.172.bbb eq 5050

access-list outside_in permit tcp any host 203.198.172.bbb eq 5001

access-list outside_in permit tcp any host 203.198.172.bbb eq 5101

access-list inside_out permit ip any any

access-list inside_out permit tcp host 10.0.51.33 any eq 5100

access-list inside_out permit tcp host 10.0.51.33 any eq 5050

access-list inside_out permit tcp host 10.0.51.33 any eq 5001

access-list inside_out permit tcp host 10.0.51.33 any eq 5101

access-group inside_out in interface inside

However while select Tools -> Start My Webcam on Yahoo messager, the same error prompted (Behind Firewall).

Any other suggestion?

Thanks for your help.

Best regards,

Jeremy Choi

Re: PIX 501 static map to enable Yahoo message' webcam

Hi Jeremy,

I presume you have the access-group command for access-list outside_in applied as well i.e. access-group outside_in in interface outside

Also, what is the error message when you run webcam on the inside?

Thanks - Jay

Re: PIX 501 static map to enable Yahoo message' webcam

Hi,

Thanks for your reply.

I have already the following entry.

access-group outside_in in interface outside

Do I need to add the following access-list?

access-list outside_in permit ip any any

While I try to run the webcam function, it just states that the computer is behind firewall and cannot use such the function.

Looking for your reply.

Best regards,

Jeremy Choi
