Cisco ASA 9.1 Site to site VPN

[shamsul77]

Hi All

Currently I'm trying to establish site to site vpn connection between my two asa (9.1). I tried to run site to site vpn wizard and upon setup completed I do not see any active VPN session on monitoring windows.. I do not see any session on my both Cisco ASA. Attached is the screenshot of my ASA ASDM. 

Below are the detail of my ASA detail:

ASA 1 

Ouside interface: 50.235.136.XXX

Inside Interface: 192.168.2.3

Local network which i want to allow to connect

Local Network: 192.168.1.0 / 255.255.255.0

Remote Network which i want to connect

Remote Network: 10.0.0.0 / 255.0.0.0

ASA 2

Ouside interface: 208.97.252.XXX

inside interface: 10.5.0.3

Local network which i want to allow to connect

Local Network: 10.0.0.0 / 255.0.0.0

Remote Network which i want to connect

Remote Network: 192.168.1.0 / 255.255.255.0

############################################################################

Basically my network being layout as below

Core switch (L3) for office 1 (Cisco ASA1) :

VLAN 100 :192.168.1.0 / 255.255.255.0 (DHCP)

VLAN 101 : 192.168.2.0 /255.255.255.0 (Static)

Cisco ASA1 connected to Core switch on VLAN 101

Core switch (L3) for office 2 (Cisco ASA 2) :

VLAN 100 :10.0.52.0 / 255.255.255.0 (DHCP)

VLAN 101 :10.2.55.0 /255.255.255.0 (DHCP)

VLAN 102 : 10.5.0.3 /255.255.255.0 (Static)

Cisco ASA2 connected to Core switch on VLAN 103

From ASA2 I want to connect network on Cisco ASA1 and ASA1 to ASA2 network.

There are no IKEv1 SAs

There are no IKEv2 SAs

Please do let me know if anything wrong here so that i can correct it. Thank you for the help.

Hi

First of all, on ASA 1, your local network is 192.168.1.0/24 but inside is 192.168.2.0 network. Is it a miss spelling error or 192.168.1.0/24 is behind your inside?

Other question: on ASA 2, your inside IP is 10.5.0.0 network. Why setting remote network as 10.0.0.0/8? Is there any other 10 network behind your ASA you want to be able to reach?

Then, could you share the other config part of the VPN (like nat, crypto) ?

When you try a ping 192.168.1.x from ASA 2, what logs you see on ASA 1 and ASA 2?

Thanks

PS: Please don't forget to rate and mark as correct answer if this answered your question

Cisco ASA2 connected to Core switch on VLAN 103

From ASA2 I want to connect network on Cisco ASA1 and ASA1 to ASA2 network.

[Francesco Molino]

Ok for networks. Did you do ping tests and check logs?

Could you share config of full vpn like nat, crypto?

Thanks

I'm reading it quickly through my iphone and I see an issue on your nat exempt rule:

nat (inside,ouside) source static NETWORK_OBJ_192.168.2.0_24 NETWORK_OBJ_192.168.2.0_24 destination static NETWORK_OBJ_10.0.0.0_8 NETWORK_OBJ_10.0.0.0_8 no-proxy-arp route-lookup

You're using the object NETWORK_OBJ_192.168.2.0_24 which refers to 192.168.2.0/24 and not your 192.168.1.0/24 network.

Could you modify it and try again?

You can add modify it like that:

object network NETWORK_OBJ_192.168.1.0_24
   subnet 192.168.1.0 255.255.255.0

object-group network LOCAL-LAN

  network-object object NETWORK_OBJ_192.168.1.0_24

  network-object object NETWORK_OBJ_192.168.2.0_24

!

no nat (inside,ouside) source static NETWORK_OBJ_192.168.2.0_24 NETWORK_OBJ_192.168.2.0_24 destination static NETWORK_OBJ_10.0.0.0_8 NETWORK_OBJ_10.0.0.0_8 no-proxy-arp route-lookup

[Francesco Molino]

As you paste again your config, that says it's not working?

What about the config of the other end ASA? Just attach the txt file please.

What do you see on logs?

Thanks

[shamsul77]

attached is ASA 2 config. I'm finally able to connect both ASA now..  :) but im not able to ping any of ip on ASA2 from ASA1 and ASA1 to ASA2 network. 

[shamsul77]

My current site to site connection session as attached screenshot.

[shamsul77]

You can get full config file for both ASA on my initial post. Please scroll up.

Right now im able to see active site to site vpn connection as below.. but not able to ping any network from ASA1 to ASA2 network.

[Francesco Molino]

Ok from ASA2 you can reach 192.168.1.x, right?

Now what are you trying to do? Could you test ping ASA2 lan from your 192.168.1.0 subnet and tell me if it works?

Thanks

[shamsul77]

From ASA2 to ASA1 ping 192.168.1.1 gateway failed

CISCOASA5508-X# ping 192.168.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.1, timeout is 2 seconds:
?????
Success rate is 0 percent (0/5)

I'm not able to ping any of segment from ASA1 to ASA2 network and ASA2 to ASA1 network. 

[Francesco Molino]

Please try directly from a host on your lan on both side (don't ping asa) and take logs to see what asa says

[shamsul77]

I'm still not able to connect the vpn. Attached is my latest config for both ASA1 and ASA2. you help highly appreciated.
