Palo Alto UNAT Configuration – Step-by-Step Lab Guide (LAN → DMZ via WAN)

Posted on December 16, 2025 by Gkhan

Introduction

In real-world enterprise networks, it is common to access DMZ servers using a public IP address, even from internal LAN users. This design improves consistency, simplifies DNS, and mirrors real internet access behavior.

In this blog, I will demonstrate User NAT / Destination NAT (UNAT) configuration on a Palo Alto Networks firewall using a practical lab setup with LAN, WAN, and DMZ zones.

This guide explains how traffic from a LAN PC reaches a DMZ mail server using its public IP, with UNAT applied on the firewall.

FortiGate Tip: How to Change WAN Web Access Port After Configuring IPsec VPN

Posted on November 15, 2025 by Gkhan

When you configure an IPsec Site-to-Site VPN on a FortiGate firewall (especially models like 40F, 60F, 80F), you may suddenly lose access to the web GUI on the WAN interface (port 443).
FortiGate also shows a warning during IPsec setup that HTTPS access on the WAN may be affected.

This happens because the VPN configuration can modify interface roles, local-in policies, and route priorities — which sometimes blocks the default management port (443).

How to configure Tata SIP trunks in VICIdial — registered and peer setups (safe examples)

Posted on October 17, 2025 by Gkhan

Quick overview: Register vs Peer

Registration (client registers to provider)

  • Your VICIdial server authenticates to the provider by sending a REGISTER.
  • Useful when provider expects a dynamic/unknown IP on your side or requires auth.
  • You’ll typically provide username, secret, and a register => string.

Peer / No registration

  • Provider accepts calls from your server IP without you performing SIP REGISTER.
  • You configure the provider as a SIP peer (host=provider.domain), and they accept INVITEs from your IP.
  • Preferred for fixed-IP servers — slightly simpler and often more reliable for direct routing.
