Setting up IC Web Client in CRM 5.0 SP06

Hi Experts:

I am trying to set up IC Web Client on our CRM server. The CRM consultants have already set this up in SE80. However, after calling the transaction CRM_IC, i enter the user name and password, but 60 seconds after that I get the time out error with the following message:

Detail: Connection to partner timed out after 60s

I beleive that this is happening because the following parameter hasn't been set up in the instance profile:

icm/server_port_0 = PROT=HTTP, PORT 1080, TIMEOUT=30, PROCTIMEOUT=600

However, I am not sure on the Port number, should it be 1080 or 80<Sys No.>

Please let me know what I should do here

Thanks

Imran
