Cisco PIX 506E Config Assistance 1

[Ferbert]

Hello All..... I am a Cisco Newbie - used to configure unix based firewalls a while back, but this one is new to me.

Set up - here is my current set up:

Cable modem - inside IP on cable modem - 71.12.111.217

I have a set of 5 external IP's for my use - 71.12.111.218 - 222.

Inside network 192.168.1.X 255.255.255.0

I have the set up below that I thought would work, but I cannot get any traffic to the outside. Any help would be appreciated.

[unclerico]

Your route inside 0.0.0.0 0.0.0.0 71.12.111.117 should be route outside 0.0.0.0 0.0.0.0 71.12.111.117. Also your NAT statement should be nat (inside,outside) 71.12.111.119 ferbweb

 

[unclerico]

Sorry, it should be static not nat in the last sentence there

 

[Ferbert]

Thanks - that worked great. I can get to the outside now with no problems.... BUT....

I have a web/e-mail server that is being blocked on the outside. It has the name ferbweb in the config. I need port 25 and 80 open for internet users to be able to get to the web site, and e-mail servers to deliver mail. Neither works with the config. I have supplied a new show run below.... thanks again for your help!

i would do the following:

name 71.12.111.219 ferbwebpub

no access-list outside_in

access-list outside_in permit tcp any host ferbwebpub eq www
access-list outside_in permit tcp any host ferbwebpub eq smtp
access-list outside_in permit udp any host ferbwebpub eq www
access-list outside_in permit udp any host ferbwebpub eq 3389
access-list outside_in permit tcp any host ferbwebpub eq 3389

Ok - entered that code - and it still deosn't work getting from the outside to the inside. Getting from the inside to the outside still works great. Any other ideas? Please know - I really do appreciate your help on this. See the new show run below:

[unclerico]

looks like the ACL has not been applied:

access-group outside_in in interface outside

Hey UncleRico - thanks for helping me with this. I will add this statement in the configuration, and put the appliance back into service later today and test it, and let you know what happens. Thank you again for the help! More to come.....

 

[Ferbert]

Thanks unclerico - your help was great! My PIX is up and running. Thanks again!
