Level 1

Hi Community,

 

I am stuck in here as, VPN is successfully established between DC & Site1 but traffic (icmp or any other) is not flowing. Kindly help. Below are the two site IKV1 configuration.

 

Site 1: 


object-group network Datacenter_nw
network-object 192.168.20.0 255.255.255.0
network-object 10.55.1.0 255.255.255.0

 

object network LAN
subnet 10.184.2.0 255.255.255.0


access-list SEATFWtoDatacenter extended permit ip object LAN object-group Datacenter_nw

nat (inside_1,outside) source static LAN LAN destination static Datacenter_nw Datacenter_nw no-proxy-arp route-lookup

crypto ikev1 policy 10
authentication pre-share
encryption aes-256
hash sha
group 2
lifetime 28800


crypto ikev1 enable outside
crypto isakmp identity address

tunnel-group x.x.x.x type ipsec-l2l
tunnel-group x.x.x.x ipsec-attributes
ikev1 pre-shared-key *****

crypto ipsec ikev1 transform-set myvpnset esp-aes-256 esp-sha-hmac

crypto map SEATVPN 1 match address SEATFWtoDatacenter
crypto map SEATVPN 1 set peer x.x.x.x
crypto map SEATVPN 1 set ikev1 transform-set myvpnset

 

IKEv1 SAs:

Active SA: 1
Rekey SA: 0 (A tunnel will report 1 Active and 1 Rekey SA during rekey)
Total IKE SA: 1

1 IKE Peer: x.x.x.x

Rekey : no State : MM_ACTIVE
Encrypt : aes-256 Hash : SHA

There are no IKEv2 SAs

Hi Hulk,
It was already noted the networks were inconsistent and amended.

Inconsistent networks would usually cause an issue when establishing a VPN, in this instance the tunnel was actually established so this doesn't appear to be the issue here.

oh yea, sorry, i missed that above.
