Question

Cisco PIX and 837

Asked by: boomerbostock

I've just got hold of a pix for my SOHO and wish to instal. Cisco PIX Firewall Version 6.3(4) Cisco PIX Device Manager Version 3.0(3) I cannot connect to the PDM, Java version issue i think so Im stuck with CLI configuration. I have a Cisco 837 that currently gives us intenet and i can see where the PIX fits after reading the Cisco config guide. However I cant seem to get traffic flowing inbound/out when i drop the PIX in place. I'm trying to read up on configuration, Access-lists etc but I getting stuck. Can anyone help? - Pasted config of PIX & 837 below. We have no need for DMZ we only have 5 desktops behind the PIX.
Im not sure where I'm going wrong...

On the pix, the ip route should point to the gateway address for its outside interface

 

by: rsivanandanPosted on 2009-09-20 at 08:11:41ID: 25377520

1. Are you removing the 800 and putting the PIX in?

2. What kind of connection does the ISP give you?



Cheers,
rsivanandan

I wasnt planning on moving the 800 if i can use it - i do have another modem which i could just bridge across to the pix if needed i just thought use the 800 - My ISP gives me Perm IP address on an ADSL not sure if PPOE or PPPOA

 

by: rsivanandanPosted on 2009-09-20 at 20:50:33ID: 25380212

Okay, good enough.

---Lan----PIX----800---ISP

This is what you're doing right?

So couple of things;

1. Leave the 800 config as it is;

2. On the PIX, change these 2;

>>ip address inside 192.168.1.1 255.255.255.0

ip address inside 192.168.1.2 255.255.255.0

>>route outside 0.0.0.0 0.0.0.0 10.1.1.1

route outside 0.0.0.0 0.0.0.0 192.168.1.1

That looks pretty much to be it. Let us know.

Cheers,
rsivanandan
