I have just replace a DLink firewall on my DSL connection with a Cisco 501 PIX firewall. On the DLink we have port forwarding setup to forware &quot;IP&quot; protocol for port #1050 to an internal machine on our LAN (with IP address 192.168.0.114). I need to know what would be the proper way to do the same forwarding on a Cisco PIX. I see examples of things like:<br />
static(inside,outside) tcp interface http 192.168.0.114 http netmask 255.255.255.255 <br />
<br />
and correspondingly<br />
<br />
access-list outside_in permit tcp any interface outside eq http<br />
<br />
but the port forwarding in my dlink said protocol is IP (0) 1050/1050. &nbsp;So how does that compare to either tcp or udp?<br />
<br />
thanks terry<br />

Thank you for your help.<br />

pix firewall and port forwarding

Software firewalls, also known as host-based firewalls, provide a layer of software on one host that controls network traffic in and out of that single machine. Most operating systems now include firewall software, but many available software firewalls include central distribution, antivirus systems and disaster recovery.

Software Firewalls

Cisco PIX is a dedicated hardware firewall appliance; the Cisco Adaptive Security Appliance (ASA) is a firewall and anti-malware security appliance that provides unified threat management and protection the PIX does not. Other Cisco devices and systems include routers, switches, storage networking, wireless and the software and hardware for PIX Firewall Manager (PFM), PIX Device Manager (PDM) and Adaptive Security Device Manager (ASDM).
