VPN Through ASA - what to allow & what not ?
In vpn , how do we actually know what should be the interesting traffic...
say , r4 , asa2 , r5 are there.. the gre tunnel should pass eigrp 45 multicast packets exchanging info abt loo.
then how do we actually know what to allow/permit on ASA2 .. whether it is isakmp/500 or esp or gre..!!
Thank u in advance..!!
