Level 1

Hi,

If anyone can help it will be greatly appreciated.

Short of downloading a packet anaylser and finding out why my uploads are not working i am having trouble attaching attachments to web emails and uploading to FTP sites from a PC inside my LAN - They timeout!

My modem is plugged into the AUX port and i have no problems browsing the web but continually have problems trying to send data in the form of attachments and FTP.

My config shows:

interface FastEthernet0/0

ip address 192.168.128.254 255.255.255.0

ip nat inside

duplex auto

speed auto

no ip mroute-cache

I am thinking it has something to do with the way i initiate sessions but why isnt http affected?

Please help!

I suspect the flow control setting is giving problem for u. Try both the Hardware and Software setting and do the attachment.

Thanks.

I'll try it. But why isnt http traffic affected?
