I have remote 851 routers that will get dynamic IP addressing from the ISP. These 851's will terminate their vpn connection into an ASA5520 that gets static IP addressing from the ISP. I had started to look into L2L Dynamic VPN's but was told that it is best to use EZVPN. My question is, can EZVPN allow our remote 851 routers communicate with each other in a spoke to spoke configuration (Cisco Hairpinning)?
I have this problem too.
