I work for a company that provides network support for SME's.
Currently we have a fairly standard set up that we install at the perimetre for most clients - we use a PIX 501 and a cheapy netgear ADSL router (of whatever variety is available that month, as they seem to change at a rapid rate)
This generally works - I particularly like the PIX for the following reasons:
1: No-nonsense vpn client. Easily configured & supported.
2: Decent nat-traversal support for IPSEC so that people can connect to the vpn over gprs, 3g etc
3: Ability to connect to radius for authentication of vpn clients
Recently I've had a few issues with the netgears, mainly firmware things to do with them not correctly routing public IP's on the lan interface, and they are generally a cheapy crappy unit - seem prone to overheating and general crashes. Probably fine for home - but I don't think they are really business class.
I'm considering getting a Cisco 800 series adsl router so that we can combine this functionality into one reliable unit.
Will the 827 be a suitable replacement for both boxes (pix&netgear), or am I missing something?
