Cisco PIX 506 outside access to a machine

Please show the wqhole config and we tell you the lines that you need!

Please refer this guide howto:
http://www.netcraftsmen.net/resources/archived-articles/369-cisco-pix-firewall-basics.html
http://www.linuxhomenetworking.com/cisco-hn/dsl-pix.htm

OK here's the config, there is a load stuff in there from some old static VPNs. The last time I tried to remove them them firewall crashed!

Result of firewall command: "sho run"

HI,

The config seems good, the follwing that enable proxy arp need:

sysopt noproxarp outside

Thanks for that.
I tried the command, then write mem and a reload. However still no joy.
The machine is a video monitoring device listening on ports 4580 and 4599. It works fine from inside the network, but we need an external alarm company to have access.
I can ping 217.36.99.43 from outside but cannot (say) telnet to it.
I must be missing something simple here.

only this source address allowed from outside:

access-list outside_access_in permit ip host 217.36.99.43 host 217.36.99.43

Yes that would be what I am trying to achieve. With that address visible outside, routing through to 10.1.1.202 which is the machine I want to 'hit'. Preferrably on ports 4580 and 4599, but anything for the moment!

what shows the log?

I get :
date time 106023: Deny tcp src outside:xxx.xxx.xxx.243/35804 dst inside:217.xxx.xxx.43/4580 by access-group "outside_access_in"

I know xxx.xxx.xxx.243 was my testing source ip address. Interestingly I also have the same message from an 'unknown' source ipaddress. Someone else following this thread?

but you entered x.x.x.43:
access-list outside_access_in permit ip host 217.36.99.43 host 217.36.99.43


you need :
access-list outside_access_in permit ip host x.x.x.243 host 217.36.99.43

and CTRL Z
clear xlate

Please remember I'm a real beginner on PIX's, but I think the light has come on.
The x.x.x.243 address was the machine I was using to 'probe' my firewall. In the future I will not know the address(es) of the machines that will access in.
Should the command read something like :
access-list outside_access_in permit ip host any host 217.36.99.43 eq 4580
and
access-list outside_access_in permit ip host any host 217.36.99.43 eq 4599
??

Thanks to ikalmar and nkwizz.

The PIX is functioning as required, although it appeared to hang up overnight and required a power off to reset it. Not surprising bearing in mind how much futzing around I've been doing!

Although a solution that would work I implemeted a service group for the two ports to simplify the access-list.

HI,

Mi comment is aloso good: ID: 26600938, but i didn't cath points:(
