Unified Access Gateway supports multiple use cases: This can be done by loading wireshark on the connection server or desktop and running a capture from there.VMware Unified Access Gateway ™ is an extremely useful component within a VMware Workspace ONE ® and VMware Horizon ® deployment because it enables secure remote access from an external network to a variety of internal resources. Last you can use wireshark to check connectivity from the desktop or connection server. Using tracepath to trace the route of network hopes between UAG and Internal network resources: If UDP is blocked then run the following to check if the traffic has failed over to TCP Run the following to test UDP 22443 connection between UAG and Desktop Run the following command to test port 8443 connection between external client and UAG. Run the following command to test port 443 connection between external client and UAG. The below commands assumes that only one NIC has been configured on the UAG if you are using more then one NIC you will need to change eth0 to the correct eth port. After logging into the console of the UAG run the following /etc/vmware/gss-support/install.sh at the command line. This seems to be included in UAG 3.2 version.
Using tcpdump to test UDP ports between UAG and Internal network:Īfter working on a issue I learned from VMware support that you can install tcpdump on a UAG. Using the below commands to do this task. Next you can check to see if TCP ports are open between the UAG and Connection server / Desktop. Using curl test TCP ports between UAG and Internal network: Ping one of each of your desktops per subnet.Ping the load balanced VIP for Internal connection servers.This should be tested for the following items. Next check basic network connectivity with ping by running the ping command from the UAG console. Using Ping to troubleshoot UAG network issues: Should also check that your External URL can be resolved on public DNS.
Load Balanced VIP for Internal Connection servers.This should be tested on the following items. Another tool that might help is wireshark to run on your connection servers or VDI desktops.įirst make sure that DNS is working by using nslookup command from the UAG console. The options you have when doing this troubleshooting include 5 tools (Ping, nslookup, tracepath, curl, and tcpdump) from the UAG console interface. When setting up the Unified Access Gateway (UAG) for the first time you might run into network issues or trying to prove to your network team that a port is not open.
