We can not use lookback IP to communicate with the outside network! BUT. If you do send a packet from that ip, it will be ignored by other devices. If you have no gateway, or the gateway does not know where the network is, then the message is not sent.ġ27.0.0.1 is always on a different subnet to your network, routing devices will never route traffic from it, and your host machines will not try to send messages from it. A message will be sent to the gateway and the devices rely on the gateway to send over the message. However, if I have 192.168.0.1 ping 192.168.1.1, they will again look at the network portion and see it is different. If I try and ping 192.168.0.1 from 192.168.0.2 They will look at their subnet and identify their network portion of the ip address (192.168.0) They both see they are on the same subnet, and communicate. Lets assume your network is on the 192.168.0.0 subnet with the subnet mask of 255.255.255.0. If they are, they will talk, if not, they will attempt to use a gateway (router etc) to try and get there. When computers talk, they check to see if they are on the same subnet as the device they are talking to. If you ping 127.3.3.3 for example your device will ping itself. Local loopback uses the ip range 127.0.0.1-127.255.255.254Ī loopback device is generally assigned that entire range. GlobalProtect Name : gp-gateway (2 users)ĭomain User Name Computer Client Private IP Public IP ESP SSL Login Time Logout/Expiration TTL Inactivity TTL > show global-protect-gateway current-user The password in the profile will need to match with the authentication method chosen (ie ldap, kerberos,localdb, etc).Ĭonfirm access via your Global Protect client as well as your mobile device. This will be utilized when configuring the VPN profile on the mobile devices.Ĭreate the VPN Profile on the iPhone/iPad using the shared secret configured in the previous step. In this example, the gateway service group is utilized and used to forward traffic to 10.1.1.2, the loopback.2 interface previously configured.Įnable 'X-Auth Support' on the gateway and create a Group Name and the Group Password respectively. Below this rule, another rule is created to the gateway allowing ike, ipsec, panos-global-protect, ssl and web-browsing respectively.Ĭreate the NAT policy which will forward traffic to the second loopback (loopback.2) interface. Here GP portal is accessed on port 7000 instead of port 443. The two custom services are added in addition to the predefined service-https to the gateway service group profile.Īdd the services to a service group objectĪs noted in the prior KB article, a rule is needed for the Portal page to redirect that traffic on a non-ssl standard port to our first loopback interface. In this example, services were created destined for ports 500 (ike/ciscovpn), 4501 (ipsec-esp-udp). These services will be natted to our Gateway loopback interface. PING 10.1.1.2 (10.1.1.2) from 99.7.172.157 : 56(84) bytes of data.Ħ4 bytes from 10.1.1.2: icmp_seq=1 ttl=64 time=0.126 msĦ4 bytes from 10.1.1.2: icmp_seq=2 ttl=64 time=0.068 msĪssign loopback interface as the Portal addressĪssign loopback.2 interface as the Gateway addressĬreate the following services and add them to a service group. Make sure the untrust interface can ping the loopback. You'll need to create a second loopback interface in addition to the first loopback interface used for the Portal. Please follow Knowledge Base article How to Configure GlobalProtect Portal Page to be Accessed on any Port with one caveat. If you only have one public-facing IP address, and you wish to host SSL-based applications, such as OWA on that IP, the following information provides the configuration steps for doing so. In addition to using a non-https Global Protect Portal, you can access an associated Gateway on a configured loopback interface.
