Cisco router recommendation

Cisco 800 series routers are the least expensive.  They do support site to site VPN.  Different model support different WAN interfaces and a different number of VPN tunnels.  See the link for details.

Have you ever set one up for site to site ? I dont know that they do - that was my first inclination because of cost, I think they only support easy vpn.

I've never personally set them up, but on that page I referenced before, it shows some models supporting Dynamic Multipoint VPN, Cisco GETVPN, and SSL VPN Solutions.  This link will give you the data sheets on each, but some definitely support site-to-site.

Hi

this depends on your budget ..
i recommend 1800, 2800 series .. with an IOS supports IPsec
and i can help you well in setting up site to site VPN..
how many sites you need to configure .. ??

Thanks Memo.

Currently 3 sites and am using 851 routers at all 3 but am finding out that we need more in regards to future demands...i.e vlan support (trunking). I currently have an a 2800 in the lab that wasn't hard to configure, you say 1800's will do the trick as well ? how about asa5505, I heard was also a good endpoint and has some routing capabilities.

Just FYI - remote sites are small businesses about 15-20 employees.

for sure ASA5505 is good and i didnt mention it as per your question ,, i thought you need exactly need  ..

also ASA can handle the issue and i can help you in its configuration ..

I thought it would be cheaper solution than the 2800 series but that's only because I priced it with the base license.
