Solved: VPN S2S/L2L between 2 ASA 5505 Packet tracer

Hello, I'm new in the community of packet tracer.

I am trying to create a VPN between 2 Cisco ASA 5505 (Site to site) via packet tracer.

2018-02-14 10_32_24-VirtualBox.png

I would like my PC from my Site 1 (192.168.1.1) to ping my 2nd PC from my Site 2 (192.168.2.1)

Unfortunately if I send a ping from my PC 1 (192.168.1.1) the ASA 5505 site 2 (10.10.10.2) blocks my package

I tried to follow different tutorial found on the net but none gives a positive result.

 

regards.

Re: Problem: VPN S2S/L2L between 2 ASA 5505 Packet tracer

Hello @MrEtho53,

 

There is no alternative in Packet-Tracer that´s what you get, nothing else. I would suggest using GNS3 or EVE-NG (better option) for your labs. 

 

Unfortunately, Packet-tracer is very limited in Firewalling.

Re: Problem: VPN S2S/L2L between 2 ASA 5505 Packet tracer

It seems you are nating the vpn packets, that will cause not to match the crypto-acl.

In order to avoid that you can configure identity nat for the vpn traffic. Should be something like:

 

ASA0 configuration:

object network LAN-remote
subnet 192.168.2.0 255.255.255.0
!
nat (inside,outside) source static LAN-inside LAN-inside destination static LAN-remote LAN-remote no-proxy-arp route-lookup

 

ASA1 configuration:

object network LAN-remote
subnet 192.168.1.0 255.255.255.0
!
nat (inside,outside) source static LAN-inside LAN-inside destination static LAN-remote LAN-remote no-proxy-arp route-lookup

Considering it is a lab and you want to test the vpn, you could remove the nat config.

 

object network LAN-inside
 no nat (inside,outside) dynamic interface
