Solving Asymmetric Routing: Accessing LAN Devices with Misconfigured Gateways

 

Issue:

Managed switch at 192.168.1.2 was reachable via ARP but "filtered" on all ports during Nmap scans over OpenVPN. The switch had a misconfigured Default Gateway (.254 instead of .1.1), causing a routing dead-end where the switch could receive packets but couldn't route replies back to the 10.8.0.0/24 VPN subnet.

Temporary Resolution (VPN):

Implemented a Hybrid Outbound NAT rule in pfSense on the LAN interface. This masqueraded VPN traffic as coming from the LAN interface IP (192.168.1.1), tricking the switch into responding to a local address. Once GUI access was gained, the System Default Gateway was corrected to 192.168.1.1 and saved to flash.

Resolution:

Update switch gateway to correct gateway. In this case it was .254 to .1

Issue:

Cannot move customer data from one machine to another without multiple useless errors.

Resolution:

As per UPS tech support, both previous and new application must be the same version. You must upgrade the old version in multiples of two versions at a time. Thanks UPS😒

Windows Terminal - Mute Bell Sound

 

Problem:

Windows Terminal has this super annoying bell sound when certain keys in the terminal window are pressed. It's more so if you tap the directional key down when there's nowhere to go....however it goes "Ding!" and if your volume is jacked, it can be quite annoying.

We're going to mute it for all profiles. There's no need to have it.

Fix:

To disable the bell sound in Windows Terminal and see a visual indicator instead, follow these steps:

1. Open Windows Terminal.

2. Right-click on the title bar and select Settings.

3. In the bottom-left corner of the Settings window, click on Open JSON file.

4. Locate the "profiles" section, then find "defaults". Inside the curly braces {} of "defaults", add the line. Make sure to add a comma after "bellStyle": "none" if it's not the last entry in the "defaults" section.

5. Save the JSON file. You shouldn't see any errors in the Settings panel now.
