- Which commands on router 2620 I must set for sending Syslog message to any syslog server ?
I use WinSyslog to be syslog server , I cannot get any message from Cisco router at all. How to troubleshoot ?

- Which port does Cisco Router use to connect to SYSLOG Server  ? Can I assign it manually ?

I use command logging a.b.c.d , logging on , logging monitor debugging, logging console debugging on Cisco.

This should work for you:

logging on
logging trap debugging
logging <ip_address_of_syslog_server>

Hope it helps.

Try adding:
logging trap informational

Does your syslog system have a route to the source address of the router? Can you ping all interfaces of the router?
You may need to specify the source address:
To specify the source IP address of syslog packets, use the logging source-interface global configuration command. Use the no form of this command to remove the source designation.

logging source-interface type number

Syslog defaults to UDP port 514. Make sure the server is listening on that port.

A comment on lrmoore's suggestion.
It would be a very good idea to use a loopback interface as the source address, as a loopback interface never goes down.
A loopback interface is generally a good thing to have. It is also useful if you run OSPF, ntp and other things.
