traffic is not passing thru the firewall

john_peter — Mon, 11 Mar 2019 14:32:44 GMT

Hi everyone,

I have two pix525's HA mode. I tried migrating the same to another vendor firewall, but due to some reasons I could not make it thru. Now, once i reverted back to the pix setup, i found none of the traffic is passing thru the primary firewall nor unable to ping, but thanks to God, it works with secondary. I do not find any config changes btw'n these f/ws. This was happened a week ago and still running with one f/w. Can any one help me in here...

hey John

Do you have more details on your network ? How is the routing happening ? Are there any error logs on the PIX ? "show log" ? If the firewalls havent changed their configs, i dont see any reason, it should fail.. and especially if it works on failover..

Is it a normal failover or stateful / LAN failover ? are the configs in both the firewalls consistent ?

Hi sachin,

well, its normal failover using failover cable. Does it matter if my pri has failover as active/active.

hello john

was there any interface of the primary which was down ? in that case, the primary firewall might never become active.. what was the issue ? did u make the primary firewall, active, in a standalone mode ? was it working ?
