From 2096da31cc70c9a94c1f5578182e2340712bf31d Mon Sep 17 00:00:00 2001 From: Claude Date: Tue, 2 Dec 2025 23:33:57 +0000 Subject: [PATCH 1/2] v1.24: Complete OPNsense/VLAN TURN configuration automation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Major improvements: 1. COMPREHENSIVE OPNsense/pfSense Guide - Complete network topology (LAN 192.168.1.0/24 + VLANs 20/30/40) - Step-by-step firewall rules for VLAN isolation - Detailed port forwarding tables (WAN → COTURN/Asterisk) - Visual flow diagrams for cross-VLAN communication - Testing procedures for TURN/COTURN validation - All rules properly ordered (Allow specific → Block general) 2. Enhanced COTURN Configuration - Auto-detects and binds to local IP (listening-ip/relay-ip) - Configured for OPNsense/VLAN environments - Added TLS support on port 5349 - Proper relay port range (49152-65535) - Optimized for NAT traversal 3. Asterisk Auto-Configuration - Added ice_support=yes to all transports (UDP/TCP/TLS) - rtp.conf auto-configures with COTURN when enabled - Automatic TURN credentials injection - Falls back to Google STUN when COTURN not configured - No manual editing required 4. Baresip Auto-Configuration - Automatically injects TURN server configuration - Uses COTURN credentials when available - Zero manual configuration needed AUTOMATION: All configurations now handle themselves automatically. Nothing requires manual editing/configuration/starting by hand. Fixes foggy instructions, replaces with crystal-clear OPNsense guide. --- ...3.sh => easy-asterisk-interactive-v1.24.sh | 289 ++++++++++++++---- 1 file changed, 227 insertions(+), 62 deletions(-) rename easy-asterisk-interactive-v1.23.sh => easy-asterisk-interactive-v1.24.sh (83%) diff --git a/easy-asterisk-interactive-v1.23.sh b/easy-asterisk-interactive-v1.24.sh similarity index 83% rename from easy-asterisk-interactive-v1.23.sh rename to easy-asterisk-interactive-v1.24.sh index b300f53..582218f 100644 --- a/easy-asterisk-interactive-v1.23.sh +++ b/easy-asterisk-interactive-v1.24.sh @@ -1,11 +1,30 @@ #!/bin/bash # ================================================================ -# Easy Asterisk - Interactive Installer v1.23 -# -# UPDATES in v1.23: -# - CLARIFIED: Router Guide now explicitly separates VLAN (Allow) vs WAN (NAT) -# - ADDED: Caddy Helper now generates snippets for both SIP and TURN domains -# - RETAINED: PTT Mute-default, Audio Ducking, Device Management +# Easy Asterisk - Interactive Installer v1.24 +# +# UPDATES in v1.24: +# - COMPREHENSIVE: Complete OPNsense/pfSense VLAN configuration guide +# * Full network topology documentation (LAN + VLAN 20/30/40) +# * Step-by-step firewall rules for VLAN isolation +# * Port forwarding tables with complete relay range +# * Visual flow diagrams showing cross-VLAN communication +# * Testing procedures for TURN/COTURN validation +# - COTURN: Enhanced configuration with listening-ip and relay-ip +# * Automatic local IP detection and binding +# * TLS support on port 5349 +# * Optimized for OPNsense/VLAN environments +# - ASTERISK: Automatic ICE/STUN/TURN integration +# * pjsip.conf now includes ice_support on all transports +# * rtp.conf auto-configures with COTURN when enabled +# * Falls back to Google STUN when COTURN not configured +# - BARESIP: Automatic TURN configuration +# * Auto-injects TURN credentials when COTURN enabled +# * No manual configuration required +# - AUTOMATION: Everything configures automatically - zero manual edits needed!

Added support for turn.example.com separate from sip.example.com - Updated Caddy cert sync to search for certs covering both domains - Supports wildcard certs (*.example.com) or multi-SAN certs - Caddy snippet generator now shows both domains when different - Config variables: DOMAIN_NAME (SIP) and TURN_DOMAIN (TURN) 2. **STATIC vs DYNAMIC IP DETECTION** - New check_ip_type_and_dns() function asks user about IP type - Detects static vs dynamic public IP configuration - For dynamic IPs, checks if user has DDNS configured - **STOPPING POINT** for users without DDNS: * Guides to popular DNS providers (Cloudflare, Namecheap, etc.) * Explains router built-in DDNS options * Lists dedicated DDNS services (No-IP, DynDNS) - **VPN ALTERNATIVE** strongly recommended: * Suggests Tailscale with installation instructions * Explains benefits: no port forwarding, no COTURN, no IP issues * More secure than exposing services - Called automatically during COTURN installation 3. **GOOGLE STUN MADE OPTIONAL** - No longer automatically falls back to Google STUN - Asks user during setup_internet_access() - New config: USE_GOOGLE_STUN (y/n) - rtp.conf generates three modes: * COTURN configured: uses local TURN server * Google STUN enabled: uses stun.l.google.com * Neither: direct connections only (for VPN setups) - Clearly explains pros/cons of each option 4. **ENHANCED CADDY CERT SYNC** - Searches for certs covering BOTH SIP and TURN domains - Validates cert coverage for each domain separately - Provides helpful hints if cert not found (wildcard or multi-SAN) - Handles same-domain scenario (TURN = SIP) efficiently - Displays which domains were covered in success message 5. **CONFIGURATION VARIABLES ADDED** - USE_GOOGLE_STUN: Enable/disable Google STUN fallback - IP_TYPE: "static" or "dynamic" - HAS_DYNAMIC_DNS: "y" or "n" - All saved to config file for persistence ADDRESSES USER CONCERNS: - "Do I need turn.example.com?" → Yes, supported now - "What about dynamic IP?" → Guided through DDNS or VPN setup - "Google as fallback optional?" → Yes, user chooses - "VPN automation?" → Kept simple, just suggestions (too fragile) All changes maintain full automation - no manual file editing required. --- easy-asterisk-interactive-v1.24.sh | 209 ++++++++++++++++++++++++++--- 1 file changed, 189 insertions(+), 20 deletions(-) diff --git a/easy-asterisk-interactive-v1.24.sh b/easy-asterisk-interactive-v1.24.sh index 582218f..e9b5b4c 100644 --- a/easy-asterisk-interactive-v1.24.sh +++ b/easy-asterisk-interactive-v1.24.sh @@ -9,22 +9,40 @@ # * Port forwarding tables with complete relay range # * Visual flow diagrams showing cross-VLAN communication # * Testing procedures for TURN/COTURN validation +# +# -
