two firewalls?

[jbenh]

We have a Watchguard firewall as our coporate unit, but one of our software vendors will not work with anything but Cisco. I am trying to setup a PIX 501 as a vpn gateway for this supplier. I am having problems with getting the PIX to work on our network. I have setup a pc with the PIX as its default gateway in order to test the setup.

Having followed the PDM Startup Wizard, this is my config.

I removed the fixup lines here to save space and we do not need dhcp.

The client pc can not ping (request timed out) apple.com, but I can ping apple and both interfaces of the PIX from my pc.

I'm lost, is there something simple I'm missing on the PIX or is it two firewalls on the same network 11.63.240.0/20 (My Watchguard is 11.63.255.252) or something else?

Ben,

A few pointers...

Firstly, when posting a config on these forums, it is advisable to remove the encrypted strings for passwords and the cryptochecksum as it may be possible to reconstitute the cleartext passwords from these. The same goes for your real IP addresses - it's just safer to keep this info private.

Secondly, you need to add a whole VPN connection to this PIX config. See the following link for information on setting up a simple VPN:

http://www.cisco.com/en/US/products...s_configuration_example09186a0080094761.shtml

You will need to ensure that the pix at the other end of the VPN has a similar config as well - I recommend speaking with the IT administrator of your vendor and getting a copy (sanitised of course!) of their PIX information.

Another useful pointer is to look in this forum for any posting by Yizhar and follow the link in his signature to his site - you can download a tool called PIXCRIPT from there which will help create a sample PIX configuration.

Hope this helps,

HoinviP,

My first step is to get the PIX to route traffic from the inside to the outside. So I didn't include the VPN part.

I suppose you could try to decrypt my password, but if I have changed it and my ip addresses then what's the point. I just think its easier to read 11.63.240.0/20 than xxx.xxx.xxx.xxx/xx. I do understand the security issue.

We're not connecting PIX to PIX, they are going to use the easy vpn client.

I did download Yizhar's config program, but that didn't work either, hence I posted an entire config so that people could see for it.

Update,

The above config is working for all but ping. Once I get that working I'll start on VPN.

HI.

Read the testing connectivity section here:

http://www.cisco.com/univercd/cc/td/doc/product/iaabu/pix/pix_sw/v_62/config/bafwcfg.htm#11866

You can limit the ICMP types from outside to only:
echo-reply, time exceeded, unreachable, source quench.

Bye
