Sophos UTM and Cisco ASA 5005 NAT/routing


Our enviroment

My LAN= 192.168.157.x

Customer LAN 2.14.224.x

My Sophos UTM has ip and an interface with wich is a exchange LAN created between out both LAN networks

Cisco ASA has and some objetcs defined NAT, for example:

PC1 at ASA and the, a rule to route traffic to

At my Sopho there is a SourceNAT wich translates source ip to 172.16 network changing  to

Of course there is something wrong because  I can not  ping or telnet ports from my computer at 192.168.157.x

Any ideas?

I'm having trouble sorting out how things are connected.  You say the customer's network is on 2.14.224.X.  This looks like an internet -facing network address.  Are you trying to connect the two networks over the internet?  It appears you have an internal network fof 192.168.157.x.   Is the 172.16.X.X network the customers internal network?

My network is 192.168.157.x and my firewall

My customer has installed a firewall and router and it's remote network is 2.14.x.x.They use an Asa firewall  to stablish a new network between both called 172.16.x.x.

It sounds to me like you should set up am IPSec VPN between the Sophos UTM and the Cisco.
