We have set up a L2L VPN between a cisco 877 and an ASA 5505.
On the 877 side we have :
dialer 0 : connect to internet and has a dynamic IP given by ISP
Loopback1 : has a static IP from the assigned Public IP range .
Vlan 1: has a static private IP for the LAN
FE3 : Interface conencted to lan
We have the following problem.
We have applied the crypto map to the Loopback interface and with this configuration we can reach the router's internal interface ( VLAN 1 IP ) from the ASA internal network , but other than that we cannot reach any host on the inside lan of the router.
If we apply the crypto map to the FE3 interface we can ping also the internal lan but we lose half the ping and the roundtrip is high ( 500-800 ms instead of 70-80 when applied only to Loopback 1 )
So I need help on this . What should be the correct configuration to have it all working fine ?
thanks in advance
In the first configuration (crypto-map applied on loopback interface) you can try this :
no ip cef (on Cisco 877)
Cef in many versions have problems similar from your's
