I need to bring hard-wired internet to one or two rooms in our church rectory and want the cables hidden behind the plaster walls—no surface trunking or exposed staples. The run will start at the existing router closet and terminate in clean, flush-mount RJ-45 wall plates inside the target rooms. Because the walls are solid plaster, you will need the right coring bits, fish tape, and experience patching small entry points so the finish remains tidy. I plan on using Cat-6 (or better) cable, so please supply and certify the line for gigabit speeds once everything is in place. Deliverables • In-wall cable run from router location to 1–2 rooms. * Room where router exists is on the 3rd floor in storage room located on the North side of the building, must be threaded to 1st ...

I’m running OPNSense with the HAProxy plugin purely as a reverse proxy and I need a clean set-up of URL rewrite rules. The goal is to make every incoming request land on the right backend while transparently converting • plain-HTTP traffic to HTTPS, and • requests for one domain to another domain, all under a mix of conditions: some rewrites must trigger on custom headers, others on specific path patterns, and the remainder should catch anything that slips through. I already have the frontends and backends defined; what’s missing is the precise ACLs, actions and map files (if you prefer those) that will: 1. Force HTTPS with an HSTS header. 2. Swap domains without breaking existing paths, query strings or cookies. 3. Respect header-based rules (e.g., X-For...
