Hi folk, I have a PIX 525 firewall which is working completely weird.
The device is running the PIX Appliance software 8.0(4) and the problem is that some hosts from the inside can reach a server in the DMZ and others can't despite the static NAT from the inside to DMZ with their own address is declared with a netmask that reach all hosts.
I have sanity check that no firewall in the server is running
2)The ACL permiting traffic from the DMZ is good
3)I installed wireshark in the server and it receive and response the packets but the host in the inside side do not receive the answer to ping that it sent.
I ran also packet-tracer and the flow of traffic tested passed smoothly.
I ran capture packet to see if some of them are droped and nothing appears.
If someone in this forums knows that this version has a bug that make the firewall works anormally please let me know. Or if you have other suggestion or if you want to see the configuration please let me know.
