Editing Introduction to a Self Managed Life: a 13 hour & 28 minute presentation by FUTO software (section)

=== When Things Don’t Work (Common Scenario) ===

This is an open source firewall combined with self-managed SIP trunking. If something works on the first go, you should be very concerned – this likely means you are in a coma &amp; dreaming. Try to wake up. If you can’t, something is wrong.

When initial setup doesn’t work, follow this troubleshooting sequence:

# '''Clear ARP Tables'''
#* Navigate to '''Diagnostics → ARP Table → Clear'''
# '''Reset States'''
#* Navigate to '''Diagnostics → States → Reset States'''
#* States are current connections
#* Must be reset on both routers
#* Wait 90 seconds after reset (best practice)
# '''Reload Filter Rules'''
#* Navigate to '''Status → Filter →''' then click ** Reload**

==== Using Packet Capture for Diagnostics ====

# Go to: '''Diagnostics → Packet Capture'''
# Configure capture:
#* Interface: WAN or LAN depending on test
#* Port: 5060, 5061, 5062, 5063, 5064, 5065 for SIP traffic

==== Reading Packet Capture Results ====

* Example of captured traffic: 199.18.220.89 (Unitel’s IP in my case)
* You’re looking to see if the port 5060 traffic is actually being directed to your PBX. You’re also looking to see if it is even coming in at all.
