I need a Cisco router with two Ethernet ports which supports IPSEC, QoS, NATing etc. There is only 20-30 users going via this router. Which router is recommended and the IOS version?
I thought 1721 is good, but I need to download a IOS which supports VPN module. Which IOS supports IPSEC VPN for Cisco 1721? Also, 1721 comes with 32MB flash which I think won't be enough for IOS with ipsec support.
Please suggest a router model for my requirement. 1700 or do I need to go for 1800 series?
