Cannot SSH server on other side of 506E

[gchurch]

Hi There

I am struggling to configure my first pix - a 506e. I cannot get through to the webserver on the other side with some services. It works ok with http and https but not with ssh and ftp. I can ssh into the pix itself no problem but not the server on the other side.

Any help would be much appreciated.

Hi,

I'm no expert (someone correct me, I am also just learning) but I do not see any rules allowing SSH or FTP to the webserver. I do however see them being allowed to the Public Interface of the firwall.

The webserver is at 231.232.82.40 so I am hoping that this allows it -

access-list inbound permit tcp any host 231.232.82.40 eq ssh
access-list inbound permit tcp any host 231.232.82.40 eq ftp

I have also added this line -

access-list inbound permit tcp any host 231.232.82.40 eq ftp-data

still no joy. Any ideas?

Hi,

Have you tried, as a test, to allow SSH or FTP to ANY? Does it work then?

You may also want to try an FTP test with Fixup for FTP disabled.

Again I'm not sure here, but is it possible that the lines should read as such:

access-list inbound permit tcp any host 192.168.1.11 eq ssh
access-list inbound permit tcp any host 192.168.1.11 eq ftp

Hi Lou

Thanks for taking the time to help out.

Yes, I have tried 'any' on both SSH & FTP - no joy
Also tried no fixup on FTP - Still nothing

Any other ideas?

I am trying to figure out the same thing.. Maybe?



access-list inbound permit tcp any host 231.232.82.34 eq ssh

I generated a ca Key

ca generate rsa key 2048 For <key_modulus_size> >= 1024

 

[gchurch]

Doh!

It was IP Chains on the server blocking the connection not the firewall...
