Hi all! I have ASA 5505 with 8.4(2)8 software for one of my branch offices and I can't configure port forwarding It seems to be very simple, but it's not working. I use my ASA as a gateway to the internet for users in office and for site-to-site IPSec VPN to HQ. I have pppoe-enabled outside interface, but ISP gives me static routable ip address. I have server behind my firewall and I should "publish" to the WAN some of its' tcp and udp ports, but I see that no packets forwarded through ASA. I tried to configure PAT as stated in official "Cisco Security Appliance Configuration Guide" through CLI and ASDM. I also used this video(same ASA and ASDM versions) by Cisco TAC's Mike Robertson.
While troubleshooting, I put permit-any-any rules on both interfaces and permitting rule for traffic to the outside interface.
access-list inside_access_in extended permit ip any any
access-list outside_access_in extended permit ip any interface outside
access-list outside_access_in extended permit ip any any
access-list global_access extended permit ip any any
I captured packets on ASA outside interface and I have it there.
