hi all ,

(192.168.0.0/24)LAN1----------------asa1---------------internet-----------------------asa2------------------LAN2(192.168.2.0/24)
now , lan 1 can reach lan 2 by site to site vpn
but i have a question :
when i have
#sh crypto ipsec sa

my problem is ,
that my asa1 lan1 only reach asa2 if its destination was to subnet 192.168.2.0/24 , i mean if requested internet i cant reach it !!!
note that the crypto_map acl says destination "any" will go to asa2 , but why when i requested the destioantion of lan2 it responce , and if i requested 8.8.8.8 it dont reach asa2 ??
i used packet tracer to investigate , it seems as a stuck !!!
how to change the remote idnet as in the red line above ??? i think it is the issue that preventing mefrom reaching internet by asa2
agian ,
what issue in the asa has relation to the remote idnet and how i can change it ?
any help ?
regards

CSCO,
The lines below, match the interesting traffic for this VPN. You will not see a specific host address unless, you configure that within you crypto ACL. Basically you have some host in network 192.168.0.0/24(LOCAL) going to 192.168.2.0/24(REMOTE). The REMOTE IDENT is the remote network where the remote host relies, which matches your interesting traffic.
So lon story short, you have some local host in the 192.168.1.0/24 range going to some host in the 192.168.2.0/24 range.
This ACL has to do with the address you map to the match address line of you crypto map.
access-list outside_cryptomap extended permit ip 192.168.0.0 255.255.255.0 any
local ident (addr/mask/prot/port): (192.168.0.0/255.255.255.0/0/0)
remote ident (addr/mask/prot/port): (192.168.2.0/255.255.255.0/0/0)

John , have u understood my question ?
03-07-2014 06:45 AM
could the far asa (asa2) play role is estimating the remote ident in asa1 ???
remote ident (addr/mask/prot/port): (192.168.2.0/255.255.255.0/0/0)
not sure form that ?
