Where is the config wrong?

[Dudbolt]

I have spent a week trying to get a config to work, to no avail! Could someone put me out of my misery! I can ping the inside of the network and the internet from the pix but nothing can get outside!

Regards

Garrett

access-list outside permit icmp any any log
access-list outside permit ip any any log
access-group outside in interface outside

that will work.

Ah,

It's the old default deny thing again? I looked at the example Cisco Configs but they didnt show those statements.

I'll give it a try!

What cant get outside exactly? It is not necessary to allow any on the outside interface. Not only is it not necessary but it is not good security practice.

I took Cisco's default setup and was able to get the inside network able to ping out but it could not resolve any DNS address's.

The Pix is conected to a SDSL router which is the gateway. Should i specify the DNS servers? I thought that the inside workstations should use the Pix inside address for DNS?

The pix won't do DNS services. You should add either an internal DNS server or the external servers for your ISP.

dhcpd dns ***.***.***.*** ?

thats the correct command isnt it?

Garrett

 

[NetworkGhost]

You can add them via

dhcpd dns 4.2.2.1


or

dhcpd auto_config outside

That will automatically pass your ISPs DNS Servers to your PC

Hi folks,

Jut wanted to say thanks for all the help and pointers. After some time, i found out the problem. The pix config was fine except for the DNS IP addresssing. These address's were given to me by BT and it seems that they were wrong. I changed the IP's and up popped the network!

Many thanks again

Garrett
