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 http://serverfault.com/questions/567590/cisco-asa-5505-nat-or-port-forward-for-sip-voip-ver-8-4 its because the UDP ports 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. I also tried: [OK] object network NEC_DSX object network NEC_DSX [ERROR] nat (inside,outside) static interface service udp 1024 1024 NAT unable to reserve ports. ------------------------ Here is my current config : ASA Version 8.4(4) ! hostname ciscoasa enable password 8Ry2YjIyt7RRXU24 encrypted passwd 2KFQnbNIdI.2KYOU encrypted names name 24.173.xxx.xxx StaticOutside description WAN IP ! interface Ethernet0/0 switchport access vlan 2 ! interface Ethernet0/1 ! interface Ethernet0/2 ! interface Ethernet0/3 ! interface Ethernet0/4 ! interface Ethernet0/5 ! interface Ethernet0/6 ! interface Ethernet0/7 ! interface Vlan1 n
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 IP address. https://www.packet6.com/configuring-nat-for-a-public-server-using-same-outside-interface/ You have just a few users and a web server you want https://community.spiceworks.com/topic/360346-asa-5505-port-reservation-not-allowed the public to access from the Internet. Translation - this is port forwarding. The 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 command line of the ASA unable to 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 (inside,outside) dynamic interfaceEverything is looking good. Everyone is unable to reserve 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 elements; name hash: 0xe796c137 access-list Outside_access_in line 1 extended permit icmp any any echo-reply (hitcnt=0) 0x24e
takes a few minutes. Join Now I have an ASA 5505 on a back-up link that I sometimes use for testing. I need to set a static PAT translation for port 443 from the outside to an internal server. I changed the port that the ASDM uses with: ASA(config)#http server enable 4443 i even ran a "clear xlate" and a reload and I still get a "unable to reserve port 443 for static PAT" error. I cannot seem to find anything else that is using 443..... This has got me stumped...quick 5 minute task taking hours to fix :-) Reply Subscribe View Best Answer RELATED TOPICS: Exxchange 2007 Behind ASA 5505 not Receiving Mail ASA 5505 set up question ASA 5505 // Advice needed   9 Replies Poblano OP JR4993 Jul 18, 2013 at 10:03 UTC It's been so long since I did this on my end but do you still have the "http server enable 443" in the config, even though you enabled 4443, 443 might still be there: no http server enable 443 0 Serrano OP Tobakslovakian Jul 19, 2013 at 2:39 UTC Run packet tracer under ASDM and view which rule in the config is matching that traffic type (source: outside, destination: inside port 443). 0 Jalapeno OP Steve.Melcher Jul 19, 2013 at 3:48 UTC I already disabled the HTTP server...still no avail. 0 Jalapeno OP Steve.Melcher Jul 19, 2013 at 3:51 UTC The packet tracer says it is associated with the default security policy on the firewall and will not show the access rule that is passing the traffic. route look-up passes The packet is dropped because Slowpath security checks fail. Still no closer to figuring this out. 0 Jalapeno OP Steve.Melcher Jul 19, 2013 at 4:37 UTC I think the issue is AnyConnect VPN settings. Doesn't that use 443? I have never changed it...not sure how... 0 Serrano OP Best Answer Tobakslovakian Jul 19, 2013 at 4:49 UTC Could also go to advanced ACL Manager and do a service search for https and see what rule it hits. Anyconnect would be under Remote Access VPN -> Clientless SSL VPN Connection; see if that is enabled. 1 Jalapeno OP Steve.Melcher Jul 19, 2013 at 4:57 UTC Bingo. I disabled WebVPN and I got it. Thanks!! 0 Serrano OP Tobakslovakian Jul 19, 2013 at 5:06 UTC Great to hear! Thanks for the feedback. 0 Jalapeno OP Steve.Melcher Jul 19, 2013 at 5:08 UTC Once I got that, I went into AnyConnect Connection Profiles and Po
