    Hi,

    I am trying to setup VPN (client - gateway) for my uncle's office, He's got T1 coming thru Cisco 2610. What do I need to do on Cisco and RV042 in order for this to work properly? or is there any alternat setup? My cisco Knowlege is practically none existance and Linksys support is unable to assist on this issue.

    T1 --> Cisco 2610 --> RV042 (DHCP) --> Server/Network

    Your inputs are greatly appreciated!:thumbup:

    Thanks

    Peter

    First and foremost you will need to find out what version of code is on the 2610. If it is non crytpo code there is nothing you can do to make it work. Have someone with rights log into the router and get to enable mode. It will have a # after the name of the decive, i.e router#. Type in Show ver and depress enter you will get back a list of stuff but the most important is the code version will be toward the top and be listed something like 2610-K9OY6-M or something of the such. The K9 is the give away, if you see K9 it has a crypto code set installed. When you get a chance to check the code get back to us and we can check into that particular version of code for you.

    Do I even need the Cisco? Can I replace Cisco with RV042 all together? The T1 uses a RJ45, would connect that to WAN1 on RV042 be ok?

    Thanks

    Ok the cisco router in question does not do encryption itself, but all that means is that you cannot terminate a vpn on the router, it should however pass the traffic. Are you trying to use the router as a vpn or are you trying to get a client behind the cisco router to connect to the linksys router. Also no you dont need the cisco router, however if you were going to take it out of play you would need a csu/dsu that is compatable with the isp there and then you can connect the csu/dsu to the linksys router. Also just so we keep things straight, yes the connection looks like an rj45 its actually an rj48 which is pinned out differently.

    Thanks for the info. So bottom line...

    Internet ==> Cisco ==> Linksys RV042 ==> Network

    I have to find someone to program the Cisco to pass the VPN traffic to the Linksys which is behind the Cisco. From the Easy VPN Client, the port I should pass along is 443 and 60443? Does that mean I don't need an static external IP for the linksys since all traffic still going thru Cisco which has a static IP?
    If I want to make a bit complicated by making it gateway to gateway from Office to Home. Would the same port forwarding/traffic forwarding work?
    Sorry if the question sounded dumb... but I am a newb.. :)
    Thanks again for your help! You have been great!

    The router will inherently pass all the traffic by default, the only thing you would need to be concerned with is if there is an ACL (access-list) in place that might block the traffic in question. As far as Quickvpn goes thats a good question, i have been trying to figure out what ports it uses myself. I do know it uses 443 or 60443 initially then the ESP packets are sent via port 4500 udp i believe. Hopefully some quickvpn master (DocLarge) can answer this one. Also if you want to send me your router config (off line of course) i will be happy to look at it for you. Oh and if you are going gateway to gateway you will not need to forward anything for the tunnel as it will be terminating on each gateway device.

    The cisco router can definitly terminate a vpn tunnel.

    First you need to get an ios that will support ipsec tunnels on the cisco router.

    Then you can search on the cisco website for topics on doing ipsec tunnels and go from there.

    Depending on the ios you may need to purchase a license for an upgraded ios that will support tunnels and go from there. If you can't get your hands on an upgraded ios, you maybe better off to just put a rv042 in front of the 2610 router and run it like that instead. Honestly if you have no cisco experience that would probably be easier anyway as a cisco router can get a little technical.

    Hope that helps a bit.
