#Airport extreme port how to#
I have not tried this because I don't know how to configure the VPN client to try to connect on these ports. alternative ports, e.g., on the router forward 22 to 500, 80 to 1701 and 443 to 4500.I think VPN in Server.app is working as I can connect to it on the internal network. This confirms that my ISP is not blocking VPN traffic, that the VPN server is working (for internal and external clients), and that the Airport Extreme is the problem.

taken the router out of the loop and connected the Mac mini directly to the cable modem.ensured Back To My Mac is disabled on the router and the Mac Mini (indeed, I don't believe Back To My Mac exists as such on High Sierra).ensured IP ranges do not overlap (as suggested also in above post): wired static from.enabled IGMP Snooping as suggested in this post: VPN Passthrough problems with Airport Extreme.I think something has gone wrong on the router. I do not think my ISP is blocking VPN traffic as this setup worked less than a week prior to the network mishap. This is the case both inside and outside the network whether I use my modem's external IP, a dynamic hostname (provided by ), or a subdomain on a CNAME entry for a DNS record I have control over. Attempting to scan for open ports on the Mac Mini from inside the network reveals the same situation. If the problem continues, verify your settings and contact your Administrator.Īttempting to scan for open ports on the router from outside the network reveals the ports for the other services (22, 80, 443, etc.), but none of the VPN ports (500, 1701, 4500, or 1723). I am able to connect to the VPN service from within my network, but outside the network (e.g., iPhone over cell network) I receive the error message: I have a forwarding rule for VPN setup on the router (UDP ports 500, 1701, 4500 TCP port 1723), and the VPN service within Server.App enabled on the Mac Mini. Connect the drive to a USB port on your AirPort base station, then turn it on. Connect the drive directly to your Mac, then use Disk Utility to erase it. Since its not a USB disk, its not what most people would call an AirPort Extreme shared disk' - that term usually refers to a USB disk plugged into an AirPort Extreme, for which the AirPort Extreme Base Station acts as the AFP and SMB server. I have had success forwarding various services (ssh, http, https) from outside the network to the Mac Mini. Time Machine can back up to an external USB drive connected to an AirPort Extreme Base Station (802.11ac model) or AirPort Time Capsule. Now, everything appears to be working except for VPN. Neither the physical topology of my network has not been altered, nor have the IP addresses of devices on my network changed. Before I noticed this was due to a 8 port hub losing power, I factory reset the router (unplugged power, held down reset button, plugged in power, waited for lights to start blinking, and reconfigured router). Mac (no offense intended, but please allow me to go mental for a while) - What about an "advanced config" option? What about a product that satisfies both geeks' and regular users' needs.Following a factory reset, is my Airport Extreme 2013 no longer forwarding VPN traffic?įor years I have hosted a VPN from my home with various versions of Server.app (currently 5.6.3, latest for High Sierra) on various versions of OS X (currently 10.13, High Sierra) installed on a Mac Mini, wired through various ethernet hubs/switches to an Airport Extreme router (2013, 6th Generation running version 7.7.9). In other words: Apple thinks you're a lamer that only want to surf the Internet and use. One for dns name resolution requests coming from the Internet, and another one for the LAN. Another technical workaround would involve enabling two separate DNS views (Bind 9 or higher). This is far from being a coherent solution, so my domain got back to Network Solutions' own servers. The problem was solved when I used my linux box internal IP as preferred (and only) DNS in the admin GUI. This service passes on all incoming DNS/UDP requests to the hosts specified in the configuration GUI. Why did this happen? After much pain and woe, I found that the base station has a running, hidden and undocumented DNS caching/forwarding service, listening at port 53 udp. due to Canadian wildfires could delay flights through Boston, New York, Philadelphia, Baltimore, and. However, NAT seems to work just fine for http(s) and mail. The FAA also said the extreme wildfire smoke haze lingering over the Northeast U.S. I don't know what you're trying to do exactly, but I'll explain my case (and how I solved it)Ġ) I host my own DNS/mail/web domain in a linux box at home.ġ) I replaced my ol' router with a brand-new, sleeker Airport Express Base Station 802.11nĢ) As I did before in the router, I forwarded all incoming traffic to my linux box (NAT-PMP)ģ) DNS (port 53) name resolution uses UDP requests.Ĥ) The ABS GUI wouldn't let me forward port 53 udp(!!).
