Unanswered Question

I have a WAN with 5 Cisco 1841 routers with DRAM/Flash 191/32. I need an IOS with Qos, VPN & NAT functionalities. I am looking at the following codes



From the looks of it the first version of code could do the trick, but I think it's better to ask for some advice. The second question I have is will the VPN in Cisco IOS enable me to have a VPN tunnel between all 5 routers at the same time or will it only allow 1 tunnel to be configured between any 2 sites?

Thanks in advance.

Both flavors will meet your listed needs. When selecting IOS' I like to keep the footprint and demaind on resources as small as possible. If you don't anticipate needing the features of Advanced IP Services over the next 12 months I'd go with Advanced Security.

Also, look for known bugs and test the IOS before you deploy it.

Hi James

Do you know if the IOS & 1841 routers can handle VPN tunnels or not connected to each other or not? (ie all 5 routers connected to each other simultaneously using the VPN functionality)

Yes, the 1841 and either IOS can support a fully meshed VPN between all 5 Routers.
