How to test internet port

    Where I work we have a linksys broadband firewall router with 4-port switch and VPN. The router is between our LAN and our link to the internet. The router was set up by a IT guy who happens now to be on vacation. Lately we have no internet connectivity. I don't know if the problem is in our equipment or the ISP's equipment (radio transceiver). (It's either the router or their equip.) I can ask the ISP to find the problem but if it's our router we pay for it.
    So. I'm trying to test ports. (I don't have a router password nor do I know how to program the router.)
    I can connect two workstations by cable through any two of the switch ports. I can ping either one from the other.
    However, when I connect one workstation to a switch port and the other to the internet port, I cannot ping the workstation connected to the internet port, from the other. This is suspicious because when the whole system is working I can ping any IP address on the internet. However, I don't know if the router firewall simply won't pass the ping through.
    Can the router discriminate between sending to the internet versus sending to a workstation?
    I guess the question is, should I conclude that our router has a bad internet port, or not? What other tests can I make? Thanks for suggestions.

    OK. That was too remedial a question. Now the problem is in the hands of those responsible to fix it.
