Need help port Forwarding a pix 501

[Ceejay999]

Hello, and thanks for taking the time to look over the thread. I need some help getting a pix 501 to port foward to a DVR behind it.

The Pix is responsible for the VPN as well, so i am a bit nervous of getting anything wrong on this one. We have a Wide Area network setup all throughout the city all connected through cisco's and VPN's. I, unfortuantely, lost my cisco guy, and need to get a DVR visible remotely quickly for the police to have access to it via the web.

This is the setup.

Comcast business class Modem with static IP of A.B.C.D.

Connects to a cisco pix 501, which acts as the connect point for the VPN behind it. Acts as the gateway 192.168.20.1.

Behind this in the network is a panasonic WJ-616 DVR with IP address 192.168.20.255 with port access on port 93. This is the thing I need to get access to the outside.

I can handle the port forwarding from the comcast to the pix with little issue, and I know a few of the basic cisco router commands for port forwarding, but the PIX seems to be a different beast.

With the comcast modem forwarding A.B.C.D:93 to the Pix, what would i need to add to the config of the PIX to then forward that to the DVR behind it?

Any and all help is greatly appreciated, thank you!

Hi chris,

you can try these command if it is TCP use tcp otherwise UDP in place of tcp below.

ip address outside
ip address inside 192.168.20.255  255.255.255.0
static (inside,outside) tcp interface 93 192.168.20.255 93 netmask
255.255.255.255 0 0
access-list WEB_SERVER_ACL permit tcp any interface outside eq 93
access-group WEB_SERVER_ACL in interface outside.

please mark this answered if this help.

thanks

Well this didn't work, heh. It brought the whole site down. Rather obvious wh

y when i look at the running config. So i figured I'd best post that.

I have to admit I don't know what half of it does. :/

here is the PIX's current Running Config: ( i changed two IP's to 10.10.10.10 our static IP, and 20.20.20.20 which is the VPN static IP at our main site)

sorry about bringing the site down....didnt know you had dynamic IP on outside interface ,also i dont c any access list applied in your config so let me rephrase the config you can try .

ip address outside dhcp setroute retry 4
ip address inside 192.168.20.1 255.255.255.0
access-list inbound permit tcp any any eq 93
access-list inbound permit udp any any eq 93
global (outside) 1 interface
nat (inside) 1 0.0.0.0 0.0.0.0 0 0
static (inside,outside) tcp interface 93 192.168.20.20 93 netmask 255.255.255.255 0 0
static (inside,outside) udp interface 93 192.168.20.20 93 netmask 255.255.255.255 0 0
access-group inbound in interface outside

i have put 2 command for access-list and static command on for TCP and other for UDP . if you are sure about the protocol (TCP/UDP) you can enter just that one.

if this also didnt help ...i would suggest putting up this question in Firewall section.

regards

karan

Thanks again for your help. It did not work, but due to time constraints of having to get this viewable, I just

ran a new line through the wall directly from the modem.

Thanks again for trying though.
