I am assuming that in order to reach the site through the pix i need to open a port or fixup. Any solutions?

Hi,

You'll need a ACL on the inside interface for your inside client to connect to the mentioned port, i.e.

access-list inside permit tcp host any eq 8443

access-group inside in interface inside

You'll need to save with write mem and also clear translations with clear xlate

If the connection is made back to you then you'll need a static and ACL on you PIX to allow the connection to you inside network.

Hope this helps and let me know how you get on.

Jay

I tried it and found that I could no longer reach anything from the inside to the outside.

Hi,

Sorry a little lost here, you say that when you applied that ACL you don't have access from inside to outside. Did you issue command clear xlate, if possible can you post your config here or direct to me if you like (please remember to change real IPs and passwords. e-mail: jmia@ohgroup.co.uk

Hi,

I don't see any access-group applied for your inside ACLs (access-list outbound-nat) ? I presume your ACL outbound-nat is for the inside interface?

Can you tell me if the above asumption is correct before we go any further. If you take out the previous ACL that stopped connectivity, does evrything work ok??

Did you save with command write memory and also issued command clear xlate ??

Let me know,

Jay

Hi,

The procedure for changing the inside access-list to permit additional users access is as follows.

Open up a notepad session and also telnet into the PIX.

Show the configuration on the PIX, copy all the access-list inside (which I presume) is access-list outbound-nat lines into notepad. At the start of the text in notepad add an additional line stating no access-list inside, in your case no access-list outbound-nat

It should end up looking something like this

No access-list outbound-nat

access-list outbound-nat deny ip any host a.b.c.7

access-list outbound-nat deny ip any host a.b.c.7

access-list outbound-nat deny ip any host a.b.c.7

access-list outbound-nat deny ip any host a.b.c.7

access-list outbound-nat permit ip any any

access-group outbound-nat in interface inside

Add the additional ACL (access-list outbound-nat permit tcp host any eq 8443) you require to the start, below the no access-list outbound-nat line. If you need to take any ACLs out simply delete the appropriate line from the text.

Back to the telnet screen, make sure your in configuration mode, paste the modified text back into the PIX, issue the write memory command and then issue command clear xlate.

The way this works is when the no access-list outbound-nat command is issued the entire list and the interface (if any are applied) statements are removed. Modifying the text in notepad and pasting it back ensures that the list is in the correct order, as the list is parsed start to finish, BUT if a match is made access-list processing stops. Therefore if you simply stick new entries at the end of the list they will be ignored because of the catch all access-list outbound-nat permit ip any any at the end of the list.

Hope this helps, Jay.

i did what you said ..

nothing different is happening.

I tried using the inside client ip as (eg.10.a.b.c)

i then tried using the inside client ip as the inside interface ip ..

still no luck

Gavin,

Can you enable syslog please and capture the output.

To enable syslog do:

logging on

logging buffer debug

sho log

Either post your results here or to me : jmia@ohgroup.co.uk

Thanks / Jay.
