Basic VPN query

Brian Taylor
Beginner
Beginner

We have a 2901 running IOS 15.5(3) that used to have VPN may years ago. However there has been a request to set up a new VPN. I'm a bit rusty on this and there seem to be more Cisco options these days. So I'm after basic advice on how to proceed. For example is the 2901 VPN option still ok? Should I be looking at "anyconnect" or an ASA device? Should I upgrade the 2901? Are other options better these days? 

Also I saw this link - is this workable?

Thanks

Hello,

the first question would be: which 2901 do you have ? The ISR-G2, or the first generation router ? If you don't know, post the output of 'sh ver'. In the latter case, you cannot upgrade to a 17.x IOS version, so you are stuck with the maximum encryption (which your document seems to refer to). The biggest 'problem' will be that the 15.x version is rather outdated and does not support more modern, next-generation encryption...

@Brian Taylor the 2901 router is EOL. If you are looking to run remote access VPN you should look at the FPR1000 series hardware running either ASA or FTD image. 

A router does support RAVPN but it's traditionally more complex to setup and has less features than an ASA or FTD RAVPN.

Thanks very much for your comments Georg and Rob. I'll look at your recommendations. The "sh ver" is below but it look like a first gen router.

@Brian Taylor your hardware will support anyconnect RAVPN, with NGE. The Cisco recommended solution is FlexVPN.
