Port Forwarding

Hi there!

We are trying to configure a pix firewall 506e to redirect outside traffic to an inside machine.

We're using the following commands:

static (inside,outside) tcp 82.173.121.53 1417 192.168.10.137 1417 netmask 255.255.255.255

static (inside,outside) tcp 82.173.121.53 1418 192.168.10.137 1418 netmask 255.255.255.255

static (inside,outside) tcp 82.173.121.53 1419 192.168.10.137 1419 netmask 255.255.255.255

static (inside,outside) tcp 82.173.121.53 1420 192.168.10.137 1420 netmask 255.255.255.255

static (inside,outside) udp 82.173.121.53 407 192.168.10.137 407 netmask 255.255.255.255

access-list outside-inbound permit tcp any interface outside eq 1417

access-list outside-inbound permit tcp any interface outside eq 1418

access-list outside-inbound permit tcp any interface outside eq 1419

access-list outside-inbound permit tcp any interface outside eq 1420

access-list outside-inbound permit udp any interface outside eq 407

access-group outside-inbound in interface outside

We can see received packets on the hit count of the access list but only udp and we can't connect anyway.

access-list outside-inbound line 1 permit tcp any interface outside eq 1417 (hitcnt=0)

access-list outside-inbound line 2 permit tcp any interface outside eq 1418 (hitcnt=0)

access-list outside-inbound line 3 permit tcp any interface outside eq 1419 (hitcnt=0)

access-list outside-inbound line 4 permit tcp any interface outside eq 1420 (hitcnt=0)

access-list outside-inbound line 5 permit udp any interface outside eq 407 (hitcnt=1)

Thanks,

David

Hi,

Please paste the relevant part of the config that would include :

inside access lists , nat and the global statement.
