Linksys RV042 questions

Posted on 2009-04-08
Last Modified: 2013-11-05
I'm adding cable internet to our office which has T1 now.  Purchased an RV042 for this purpose.   I would like port 80 through the cable modem, and all other traffic through the sonicwall, maintaining the VPN.   I would like to know generally how to configure the RV042 to accomplish this.  I am not experienced with this type of thing, so thank you for the help.  I am hoping that an expert will point me in the right direction.

Unless you have access to the routing device that your sonic wall and Linksys router connect to then it will be impossible to route different ports to different devices. If all you are trying to do is have http traffic come in through the Linksys then you can accomplish this through DNS naming. Create an "A" record (host record) that points to the linksys IP address and have users use that qulified name.

Also, unless you have a very large number of people inside your network, the LinkSys RV042 router is a fast and powerful router that will do all you need. Try temporarily disconnecting the Sonicwall and Cisco, configure the RV042 and see how it works. I do the same (tunnels and all) with a Juniper Netscreen 5GT and it works fine (25 people inside). ...

Thank you broadspin, but if I direct http traffic out the cable modem (different provider) then won't it return to the same IP address?  I don't have access to either routing devices, just the RV042 and Sonicwall.  I can create DNS records using the AT&T Biz connect web site though.

Thank you thinkpads_user:  so I can configure a tunnel between the Site A RV042 and the Site B SonicWall SOHO3?  Or do I need to replace Site B firewall with an RV042?  That would be the most efficient, for sure.  I believeit's an IPSEC tunnel.  was thinking I needed two identical devices fo VPN.

The SOHO3 firewalls are like 5 yrs old.  Glad to hear your high opinion of the RV042 router.  We have 15 users at Site A and about 30 at Site B.  I think I will swap out the SOHO3 in the other location for an RV042, also.

@facutvivo - I don't know Sonic Wall well enough if you can connect it to an RV042. I do know that the RV042 is a vanilla IKE IPSEC VPN device like a Juniper Netscreen and that these devices can work together. My clients generally have Netscreen devices and one client has both (RV016 and RV082 models). I now have an RV042 as my main home router and when I get some time, I am going to hook it up to a client Netscreen.

Would it be better to replace the Sonic Wall with another RV042? Given the age of the Sonic Wall, I would agree with and support your conclusion that it would be more efficient. While you don't need it now (or in the foreseeable future), one nice feature of the RV0xx routers is that they support 99 tunnels. In one client application, we are heading toward 15 or so interconnected tunnels.

I setup an ipsec tunnel between RV042 WAN1 and Site B, then connected the cisco router directly to WAN2 of the RV042.   Seemed to work ok, so I created firewall rules similar to those in the Site A Sonicwall.  Everything worked EXCEPT I could not get FTP to connect and could not TELNET  on port 25 to the MX record of Site A.  I could telnet to the private IP though.   Something in the firewall rules I think, but WHAT??  After a long after-hour session I had to go back to square 1.

Plus side is I've learned a lot about the RV042 and feel like I"m very close to getting this working.  It was great seeing the increased bandwidth that the cable internet provides, and being able to connect through a tunnel from A to B, but still require some EXPERT help, so if anyone has suggestions please bring them on.

Thanks for the feedback. The RV082 and RV016 routers support 99 tunnels. The RV042 supports 49 where I said 99 above.

I now have my own RV042 tunnelled into 3 clients all with Netscreen 5GT boxes. It works really well and very fast (especially on my wired machine). I like it a lot. ... Thinkpads_User
