    Hi. Im new on this forum.
    I tried search solve my problem but i find similar problem.

    Before i had router Dlink Di-604. It was router without wireles.
    Few days ago i bought Linksys WRV200 router. I need to configure many option in firewall for example "port forward"

    wan 'any adress" > (router) --->
    from any adress WAN open ICMP like: ping tracert etc.

    How can i solve this problem.

    In D-link was simple. In this device i can't see that is possible.

    First off i would update your firmware to the latest available, the earlier versions are very unstable.

    You should be able to port forward within the firewall settings. Firwall>port forwading if i remember right.

    Now you can turn off the firewalls "stealth mode" also called "block anonymous internet requests" and the router will respond to ping, but there is no way to forward icmp as it is not port based. If you want to ping hosts on the inside, i would setup an ipsec or quickvpn tunnel to the wrv200 and then you can check the connectivity of your inside hosts as long as they are setup properly.

    You help me in one case. I dont want ping host behind my router. i wont ping geteway (router) it will be good.
    But i think that you dont solve my main problem. In wrv200 i can forward ports but it is 1:1. for example:

    wan any-Ip:21 move to

    but i want change port. i want:

    wan any-ip:21 move to

    In table of firewall configuration is'nt form to set port in lan address.

    I belive that you understand what i wrote, beacouse english is'nt my native language. I apologise if my english is bad.

    No worries about what you wrote, it is very understandable i just didnt read it closely enough on the first post. But as you have notice "port redirection" is not a feature on the wrv200. Is it ever going to be i dont know, I get around this myself by running another router inside my wrv200 that does port redirection and hosting what i need behind that router which will redirect. Currently there is no 3rd party support for the wrv200 and to be honest i dont even think this is something that linksys has planned for future updates.

    Out of curiosity what application are you trying to run that you are moving from a well known port to just any old port? And why couldnt you just run that application on that port to begin with?

    At this time i don't need any application, but in future i think that some customer of my LAN request me for one or more port forwarding. So then i'll need this function.
    However this is good option for running some application on non-standard ports.

    For example:

    One computer ( in LAN provide ftp server on standard port (21). You want open this server from internet, but on non-standard port. For example port open from internet is 8000. Then you need port forwarding.

    wan any-ip -> (router forward) ->

    It is possible to forward ports to some LAN IP, but the port number has to remain the same.

    So, It will not help, as the port forwarding will not change the port number.
