OpenVPN Client

Project Summary for Network Administration Specialist
Objective: Assist with establishing successful ping communication to the IP address 10.10.5.13 from an OpenVPN client.
Project Details:
• Goal: Establish a successful connection and receive responses when pinging 10.10.5.13 from the OpenVPN Client.
• Context:
• Around 6 devices are connected within the OpenVPN client, targeting the 10.10.5.13 device.
• Pinging reaches the intended destination (10.10.3.13) but continues without receiving responses afterward.
• Current setup utilizes an Edge Router with a NAT rule in place.
• Traceroute reveals the ICMP packets reach the 10.10.3.13 host, but subsequent hops time out.
• The routing for pinging 10.10.x.13 is operational in a Juniper SRX system but not in the new Edge Router setup.
Required Skills and Expertise:
• Proficiency with Ubiquiti equipment.
• VPN configuration and troubleshooting.
• Edge Router configuration and diagnostics.
• Overall expertise in Network Administration.
Note: Successful project completion requires deep knowledge of routing protocols, NAT rules, and familiarity with both Juniper SRX and Edge Router setups.

ICMP Responses are being dropped

The device at 10.10.3.13 or an intermediate device might be configured to drop ICMP replies.

Routing Issue

The device at 10.10.3.13 might not have a route back to the source or might be using a different path that’s black-holing the return traffic.

NAT Configuration

Given that there’s NAT involved, there’s a possibility that the return traffic isn’t being translated correctly or is being dropped due to a policy.
