Issue Allowing Access Through ASA 5505 Firewall

wholt
Level 1
Level 1

                I recently installed an ASA 5505 at a small business, to separate their wired business network from their employee WIFI access. Soon after the firewall installation was complete the office manager had a security camera system installed. The security camera system has a web access feature and asked me setup access though the firewall, so he can view the security system from his smart phone.

                The camera system is located on the Vlan1 (inside) and is assigned a static IP of 192.168.017.040 the web interface is accessed via tcp port 100. The ASA 5505 connects to the web using PPPoe to obtain a static IP, through an ISP provided DSL modem set to “Transparent Bridging”. After a few weeks of research and trying different configuration settings the connection still does not work. I have included the current configuration below. Any advice/instruction on what I’m doing wrong would be greatly appreciated.

Thank you,

Will

Hello Will,

Here is what you need to do:

no static (inside,outside) 192.168.17.40 192.168.17.40 netmask 255.255.255.255

static (inside,outside) tcp interface 100 192.168.17.40 100

Let me know how it goes
