RV042 VPN Site - Site question and Subnet Mask

Hi ,

I need to connecte three offices, with Linksys RV042 hardware,
In the head office, i will be hosting a Citrix application, two of the remote office, will need to access this application via the VPN Tunnel.

All locations will be connected Via ADSL2+ Link with static IP addresses assigned.

I've got some question regarding subnet mask with RV042 , i notice, it will not support 255.255.0.0?
I'm thinking i will run into problems with my setup in the head office,

Could someone please help me....I need to find a solution as my boss wants me to set this up really quick.

Head Office Setup
10.110.10.1 - 10.110.10.254 (Servers)
10.110.32.1 - 10.110.32.254 (Workstations)
Subnet Mask : 255.255.0.0

Remote Location setup 1
192.168.10.10 - 192.168.10.50 (Workstations)
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.10.1

Remote Location setup 2
192.168.20.10 - 192.168.20.50 (Workstations)
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.20.1

your "head office" setup mask does not reflect a class B subnet, why don't you change the mask to be /24... You use masking to increase/decrease the size of a broadcast domain. if you have less than 254 host in a subnet, then what the hell are you doing?

I had a flippin' hard time setting up a clients rv042's, this guy wanted to VPN with his wife in canada, and he bought two rv042's. I would only suggest doing the IPsec with no L2TP. although linksys claims it will work.

Thanks sullivanr6 ,Sorry, i can't change it to be a /24 , this is a company wide setup , I don't have the permission to do so.. I know what you mean you use masking increase/decrease the size of broadcast domain.

I guess it is not possible to do 255.255.0.0 on an RV042 then...

Could someone recommend a better VPN hardware, similar features with RV042 that will allow me to do 255.255.0.0 subnet mask, cisco will do.. but i don't have any experience with them.

Thanks guys..

Linksys RV042 site-to-site works very well and is easy to set up. Your /16 subnet mask may be a problem, but although I haven't tried it, you may be able to get it to work.
If you download the latest firmware it allows you to do 2 things which you could try.
a) For the router's LAN configuration use the 10.10.10.0/24 subnet. Then in the VPN configuration you should be able to use a /16 subnet mask
b) The new firmware lets you add additional LAN IP's and subnet. The additional subnet accepts a /16 subnet mask. You might have to create a dummy primary LAN IP and then an appropriate secondary IP and subnet mask. Again the VPN configuration does support /16 masks.
