Best VPN Solution

[bgibsonin]

We have a customer with an IP Office 406 and a remote location where we are connecting an 5621 IP Phone. The customer uses a Cable Modem at both locations. We then installed Linksys BEFVP41 VPN Routers at each location and created the VPN tunnel.

We are having quite a bit of problems with voice quality at the IP telephone set. Both cable modems are working out of the same router at the Cable Company and ping times are around 13ms to 20ms most of the time. However, the times will jump to 400-500ms from time to time. When this happens, the cable company is still seeing very small ping times on thier equipment. We are doing this ping test from a PC at the remote location to the Linksys router at the main location on the Public IP Address. We also set the ports on the Linksys that are being used by the IP Office and the IP phone to the highest priority.

Has anyone else used the Linksys VPN Routers with success? I am beginning to wonder if the processor in these routers are adequate. What other VPN hardware providers have you had success with on the IP Office remote phone setup?

Thanks,

I have a 406 with a pix at corp and 4 sites all using the BEFVP41 router. All are using 2 IP phones as well as citrix servers at each site.
Everything is running perfectly.

I'm using a Sonicwall solution in a similar set up to what you have and all is working well.

Sonicwall is nice because it is able to negotiate a VPN tunnel when one site is dynamic. My guess is both your sites are dynamic, so just set up one site with Dynamic DNS, then it becomes "quasi-static".

Depends what your budget is but I would recommend using packeteer or Total Traffic Control as we had problems with bandwidth on a similar system and TTC remedied it with the traffic prioritising section.

Kentrox is also a nice solution, but the only bad part is the pricing of the SOHO Q2300 ($899 List I think).

Kentrox is an awesome product. It's all GUI based and gives graphical QoS graphs. VPN client software is free to download and use and setup is literally as easy as a checkmark.

I have a Q2300 in front of a Toshiba CIX200 and have no problems whatsoever.

i use the kentrox at the main site and netgears at the remotes. you may need to enable qos on the kentrox. i was having issues until i did that and it works fine now.

Thanks for the input to everyone. We ended up switching the Linksys units for a Snapgear 300 from Secure Computing and everything seems to be working fine now.

I am very impressed with the capabilities on this Router for about $185.00 street price.

QOS is the order of the day here.

A ping is considered as data and thus you may well get good ping times but the voice packets are arriving late due to a large amount of data on the network.

You need to be implementing QOS here.

You may well find you get the same error using different kit, this issue may not be kit related, more network related due to data.

Having QoS implemented in the VPN routers is a must, but let's all be aware that even with that we cannot control 100% QoS once that traffic leaves the router to the public Internet.
