Unable To Reserve Port 500 For Static Pat
rise to the top Cisco ASA 5505; Can't forward port 443: Why am I getting “Error: unable to download policy”? up vote 1 down vote favorite I'm dealing with my first Cisco ASA (a 5505), using the ASDM interface. I've got to forward HTTP, HTTPS, PPTP and another port to a couple of internal servers. I'm pretty sure I've got it all figured out, and have successfully (I believe, change asdm port haven't actually tested yet ;) ) created and applied Static NAT rules for everything above, except HTTPS. Via the interface I can add the rule for 443, and all looks good, but when I hit [apply] I get the following error, and then the 443/HTTPS entry is removed: [ERROR] static (inside,outside) tcp interface 443 192.168.0.151 443 netmask 255.255.255.255 tcp 0 0 udp 0 unable to reserve port 443 for static PAT ERROR: unable to download policy I've had no problems creating my other rules, and can still successfully create other port rules (i.e.: '4434' as a test) so now I'm at a loss, any ideas? Thanks in advance. cisco nat port-forwarding cisco-asa share|improve this question asked Feb 19 '10 at 15:28 techie007 1,7181220 add a comment| 2 Answers 2 active oldest votes up vote 3 down vote accepted The Cisco ASDM runs on port 443, so you'll probably have to switch that to a different port before trying to forward 443 to an inside destination. share|improve this answer answered Feb 19 '10 at 15:53 pauska 17.2k44272 Worked like a charm!

So far, my trunks are registering and I can make outgoing calls and everything works, but incoming calls are silent (both ways). I'm assuming its because the UDP ports http://serverfault.com/questions/567590/cisco-asa-5505-nat-or-port-forward-for-sip-voip-ver-8-4 1024-1215 are not forwarded and neither is SIP (5060). What I need to do is forward the UDP port range of 1024-1215, however it seems I can't create a port map for UDP, or define a range of ports for UDP in a static Route. Any help in the right direction would be appreciated !!! (I was told ASA 8.4 would allow forwarding of a range of ports so I upgraded and now I'm a bit lost with the new commands) Using the ASDM I gave it a few tries but here were my results: [OK] object network NEC_DSX object network NEC_DSX [ERROR] nat (inside,outside) static interface service udp 1024-1215 1024-1215 nat (inside,outside) static interface service udp 1024-1215 1024-1215 ^ ERROR: % Invalid input detected at '^' marker.

CommentsIf you found this post useful you may be interested in reading the CCNA Security Official Certification Guide.In this scenario, you have a site with an ASA 5505 and one public https://www.packet6.com/configuring-nat-for-a-public-server-using-same-outside-interface/ IP address. You have just a few users and a web server you want the public to access from the Internet. Translation - this is port forwarding. The http://seotoast.com/cisco-asa-5505-nat-or-port-forward-for-sip-voip-ver-8-4/ requirements:Allow Inside users to access the Internet.Allow Inside Web server to serve http services to the Internet.Allow Outside users to visit your Web server.You get into the unable to command line of the ASA and you create objects for your Inside network and your Web server:LAB-ASA5505-01# conf t LAB-ASA5505-01(config)# object network INSIDE-SUBNET LAB-ASA5505-01(config-network-object)# subnet 172.20.10.0 255.255.255.0 LAB-ASA5505-01(config-network-object)# LAB-ASA5505-01(config-network-object)# exit LAB-ASA5505-01(config)# object network WWW-SERVER LAB-ASA5505-01(config-network-object)# host 172.20.10.100 LAB-ASA5505-01(config-network-object)# LAB-ASA5505-01(config-network-object)# exitThen you configure NAT so your Inside users can browse the web:LAB-ASA5505-01(config)# object network INSIDE-SUBNET LAB-ASA5505-01(config-network-object)# nat unable to reserve (inside,outside) dynamic interfaceEverything is looking good. Everyone is happy. Now it's time to show the world your website by creating a static NAT entry for your web server to your one and only public IP address. For this to work you have to configure static NAT with port forwarding:LAB-ASA5505-01(config)# object network WWW-SERVER LAB-ASA5505-01(config-network-object)# nat (inside,outside) static interface service tcp 80 80Configure an access list to allow Outside traffic to visit port 80 (http) to your Outside interface:LAB-ASA5505-01(config)# access-list Outside_access_in extended permit tcp any object WWW-SERVER eq 80 LAB-ASA5505-01(config)# access-group Outside_access_in in interface OutsideVerify your NAT configuration and test:LAB-ASA5505-01# show nat Auto NAT Policies (Section 2) 1 (Inside) to (Outside) source static WWW-SERVER interface service tcp www www translate_hits = 0, untranslate_hits = 2 2 (Inside) to (Outside) source dynamic INSIDE-SUBNET interface translate_hits = 6, untranslate_hits = 0You can also see the hit count at the access list:LAB-ASA5505-01# sh access-list access-list cached ACL log flows: total 0, denied 0 (deny-flow-max 4096) alert-interval 300 access-list Outside_access_in; 2
