You might want to describe what that service is...

If your unspecified service happens to use UDP instead of TCP for the 
transport, that would be the expected result.

Or it may be a binding issue, as the other responder mentioned.

If you suspect that there is port blocking occurring in the OS (an 
unanticipated firewall), you could test that by running the telnet 
daemon on the port that you intend to run your service on, and test an 
inbound connection.

If you mean among the different LAN ports on the switch, I don't think 
blocking is even possible with the stock Linksys firmware.
