Question about Cisco ASA 5505 Firewall
We have a public vlan2(0), private vlan1(100) and a dmz vlan3(50). We have 13 public IP's currently only using one of them on the outside interface. We have a web server in the dmz vlan3 with a 172.16.x.x ip.
Not sure if this is the web sever or the IOS version but it seem everyone is working fine on the network for the first 3 users, then when the 4th or 5th user turn on thier workstations the whole network seems to stop working. People from the inside cannot get out, people from the inside canot get to the dmz, and people on the outside internet can no longer hit the web server???
Not sure if this is an ASA xlate problem or if we have some other network problem internaly?? Have you hear of this kind of problem before happening with the ASA.s
Check for an IP conflict. How are you assigning the IP address on the workstations? If one of them happened to have the same ip address as the ip on the vlan1 on the ASA for example, you would have that exact issue.
Let me know how things go.

Tips for a great answer:
the whether the security level for DMZ and outside interface, If DMZ is high
security level. Please do the NAT configuration
· If it's having the same security level. Please issue the command "same-security-traffic permit inter-interface "in the global config mode.
