Cisco vpn pass-through limits?

[BlueIce]

Are there any vpn (ipsec/pptp) pass-through limits on any of the Cisco routers, specifically the 871W? Can't find any docs on this.

There shouldn't be any limitations. It's best to use NAT traversal to avoid any need for it. That puts a UDP wrapper on the vpn transport traffic (ESP).
