Firewall Configuration Issue

Hi,

i am having some issue while configuring PIX firewall in my network.

Please find the network digram for your refernce abt the setup.

As per diagram i am able to reach the firewall using inside interface ip address from remote end Lan.

but there is no traffic passing between outside to inside even if i kept permit ip any any ACL rule.

Can some one send me the basic configuration as per the network diagram.

It will be great help for me.

You forgot to attach (I think).

Also post your sanitized configuration.

Can you mention any SPECIFIC flow you are trying to test?

e.g. telnet x.x.x.x port

Also your default route statement seems to be wrong:

route inside 0.0.0.0 0.0.0.0 10.62.249.254 1

The interface you mention is 'inside' but the next-hop is actually the FW's outside interface IP??

It should be the following I guess:

route inside 0.0.0.0 0.0.0.0 10.62.248.XX

Also is your inside interface mask correct? Is it supposed to be /27?

Hi,

check your route command, it should be

route inside 10.62.242.0 255.255.255.0 10.62.248.62

also if you have done any Natting, you have to create a NAT exempt rule for the network range you dont want to b Natted.

Let me know for any help you require
