The IXrouter has internet access but doesn’t come online (SSL inspection)

Problem

The IXrouter can reach the internet, but does not come online. A company firewall does not actively block the connection.

Cause

The company firewall has SSL inspection enabled. With SSL inspection, each network package is decrypted, read, encrypted, and signed with a new certificate. This new certificate isn’t trusted by the IXON Cloud. Thus, the IXrouter is unable to set up a VPN, Configuration, and Data logging connection.

Note that other terms could be used instead of SSL inspection, like SSL decryption, SSL Proxy, Deep Packet Inspection, or Forward Proxy Decryption.

Solution

Disable SSL inspection on the company firewall for network traffic from the IXrouter (source-based) or to the IXON domains listed here (destination-based). For guidance, consult the firewall manufacturer’s documentation or contact them directly.

Some examples for specific brands:

Fortinet

Under Policy & Objects > Firewall Policy, create a new rule that has Inspection Mode configured with Flow-based (not Proxy-based). For more information refer to the Fortinet documentation.

Palo Alto

Under Policies > Decryption, create a rule of the type ssl-forward-proxy that has the action no-decrypt. For more information refer to the Palo Alto documentation.

WatchGuard

Create a firewall policy rule that doesn’t have HTTPS-Proxy enabled. For more information refer to the WatchGuard documentation.
