I have to replace a Draytech Vigor 2950 with a new Cisco device for a customer, as the Draytech does not support any more than 10 site-to-site VPNs.
I've seen that Cisco 880 Series allows up to 20 IPsec Tunnels whereas Cisco 890 Series allows up to 50 tunnels.
My questions are:
1. Is it possible to increase the number of IPSEC licenses if I buy the 880?
2. Is Cisco 880/890 Series the best deal to replace my old Draytech?
3. What about if I use an ASA 5505 + Ipsec license pack instead? Considering I don't need to configure routing protocols as the network is quite small, I could add a better firewall functionality. I don't need any ADSL functionality as well as the adsl modem is already configured.
