Hi Vaibhav,

As Nyle alluded to, there are typically 3 things you need to consider when configuring the firewall to allow traffic between 2 interfaces:

1. Permission (i.e. access-list and access-group)

2. Translation (i.e. static or nat/global)

3. Routing (i.e. route)

Based on the configuration you posted, you need to add appropriate translations for your interfaces.

For example, assuming you do not want to NAT addresses between Engineering and Developer:

access-list Engineering_nat0 permit ip 192.168.50.0 255.255.255.0 192.168.42.1 255.255.255.0

access-list Developer_nat0 permit ip 192.168.42.1 255.255.255.0 192.168.50.0 255.255.255.0

nat (Engineering) 0 access-list Engineering_nat0

nat (Developer) 0 access-list Developer_nat0

The above config would allow communication between the Engineering and Developer interfaces. You would have to update the above access-lists to include addresses for your other interfaces as well.

Here is the configuration guide for address translation:

Hope that helps.

Hi Mike,

Its working fine.now the problem with my VPN. I can establish the tunnel through 192.168.2.0 network but can not establish tunnel through 192.168.50.0 network.I check access rules,VPN configuration.I felt everything is OK with configuration.please find the 'sh run' & sh Debug output for reference
