We are moving to Cisco routers for VPN tunnels between client sites and our computer centers. On our site we isolate client networks and have independent ISP feeds for each client. As a result we need multiple routers on our site.
Features need to include the ability to sense a degredation in the primary line and the ability to automatically switch to the backup feed - features that are available on the 1841. However, the 1841 has much larger capacity than we need per client. Does the 871 offer these same features.
As an alternative, can the 1841 handle many many WAN lines (connections from the modems) and rount the tunnel traffic to the correct network with complete isolation?
