Hi again, couldnt make it work :-(
Packets from vlan 1 to vlan 2 natted, but no communication between vlan 1 and vlan 3.
Thing is that icmp request from vlan 1 reach unnatted vlan3, but icmp replays from vlan3 do not come back.
Any idea?
This is what I did:
hostname 6501
!
no aaa new-model
ip subnet-zero
!
!
no ip domain-lookup
!
no mls flow ip
no mls acl tcam share-global
mls ip slb purge global
mls ip multicast flow-stat-timer 9
mls cef error action freeze
