Port numbers in computer networking represent communication endpoints. IPSec NAT Traversal ( RFC 3947) (official) Unspecified vulnerability in Cisco ASA 5500 Series Adaptive Security Appliance 7.0 and Cisco PIX 500 Series Security Appliance allows remote attackers to cause a denial of service (active IPsec tunnel loss and prevention of new tunnels) via a malformed IKE message through an existing tunnel to UDP port 4500, aka Bug ID CSCtc47782. Mac OS X Server VPN service, Back to My Mac (MobileMe, Mac OS X v10.5 or later), Vodafone Sure Signal also use this port.Ībacast peer-to-peer audio and video streaming also uses port 4500 (TCP/UDP) Perhaps I dont need an IKE Policy at all, and just a VPN Policy I am absolutely a believer in reading the manual before asking for help, so please do direct me to any background I can read before I ask for your generous help.IPSec (VPN tunneling) uses the following ports: My current setup has an IKE Policy using a Mode Config, but has no VPN Policy set up. The start IP Address in the Traffic Selection section should have 0 in the last octet, to allow access to the entire network.įor example, if the existing LAN subnet of the FVS336Gv3 is on 192.168.1.x network, then the LAN IP address of the computer where you are using the MacOS native VPN client should be on a different LAN subnet such 10.10.10.x or 192.168.9.x network. To check, on the web-GUI of the FVS336Gv3, go to VPN IPSec VPN VPN Policies then select the corresponding VPN policy then click Edit. I have not yet configured iOS devices, as that is less critical to me that MacOS. I am certain the solution is some configuration adjustment on the FVS336Gv3 (perhaps DNS resolution as you suggest) but I have not had the time to experiment and have not received any reply from Netgear or any other community member. I cant recall how I stumbled upon this document but you could search for it.Īs I said, I can connect from my Mac laptop to my FVS336Gv3 over the VPN, and I can sendreceive email and web browse, but I cannot yet access LAN resources, such as my network storage. I was also trying to connect iOS devices (iPhone iPad) and got the same 5 min disconnect behavior. It became a lower priority (because we have alternate methods of accessing the VPN) but it remains an issue for us. I tried the same type of connection a few months back (we have an SRX5308), with assistance of Netgear support (there is a KB article that describes the setup), and though it worked (including accessing resources - perhaps you need to do something about DNS resolution), the connection would always terminate after 5 minutes,even if I was actilvely using it. Thank you and regards, - Ken (morrisonkena). The MacBook is running MacOS Sierra, 10.12.3. The client environment is a MacBook Pro, 13, 2016, Four Thunderbolt 3 ports, 16 GB 2133 MhZ LPDDR3 memory, 1 TB SSD disk, 3.3 GHz Intel Core i7 processor, Intel Iris Graphics 550 w 1536 MB. I am setting this up for the first time, so I cant say it was working fine before.īut I plan to try today or tomorrow on an iOS device as well. Is your network setup as well as the settings on your FVS336Gv3 and MAC OS X Sierra the same as indicated on the article below. I would greatly appreciate any direction to solve this problem of device access over the tunnel - Ken M. I wonder if the VPN connection is not added to the default VLAN, so cannot see local devices connected on the VLAN. Ipsecuritas Sierra Manual Before Askingīut I cannot see any other resources on the local network behind the VPN Firewall, such as my NAS, or share screen or files with local computers, all which I can do with client directly connecting to the local network.
