My site-to-site IPsec tunnel was built following best-practice guides, yet the link keeps dropping for reasons I can’t see. The firewall on my side is an Opnsense appliance, and each time the tunnel fails the logs simply show that the connection drops intermittently without any clear error codes. I may have tweaked something recently, but I’m honestly not sure which setting—so I need a fresh, expert pair of eyes. You should be comfortable working with Opnsense and, ideally, have experience on Checkpoint or other enterprise firewalls so you can think through the usual Phase 1 / Phase 2, NAT-T, lifetime, and crypto-profile culprits quickly. I can give you full access to the existing configuration, live logs, and packet captures through a remote session. The job is compl...

Configure HG8120C XPON ONU to use LAN 1 as WAN port instead of GPON, to access Internet & VoIP Server on LAN port 2 in Routing mode bet Port1 & Port 2.

I am working with an Exablaze Exanic card in an OLTP environment and I am seeing end-to-end send latency hovering around 2–3 ms with the function encapsulating all the below functions costing about 1 us. All traffic is generated through the exasock API, with calls in roughly this order: exasock_tcp_build_header → exasock_tcp_set_length → exasock_tcp_calc_checksum → exanic_transmit_frame → exasock_tcp_send_advance My sole objective is to drive that latency down as far as the hardware allows. If you have hands-on experience squeezing microseconds out of Exanic-based pipelines—whether through driver parameters, FPGA firmware tweaks, user-space memory mapping, or smarter batching in the exasock code path—I would like your help. What I can provide ...

A batch of new switches is arriving at our premise and I need reliable smart-hands assistance to swap them in without interrupting service. The job is strictly on-site and centres on a wired network setup: unplug the legacy hardware, mount and cable the replacement devices, power-test, and clear the rack of the retired units for collection. You will be guided in real time by a remote engineer who will confirm port assignments and link-light checks. No software configuration is required—just precise physical work and the ability to follow clear, step-by-step instructions while keeping everything tidy and properly labelled. Deliverables • New devices physically installed, patched and powered on • Old devices removed, boxed and labelled for return • Photogr...

I need a full CAT6 network rolled out—more than 50 drops in total. The scope covers pulling and dressing the cable, installing and terminating I/O wall boxes, fitting patch panels, mounting the switches, and finishing with clear, consistent labeling and tagging. The work will span several environments: standard office areas, a data-center room, and a few residential-style spaces, so the approach has to remain tidy, code-compliant, and adaptable. All terminations must be tested with a Fluke (or equivalent) and documented. I will provide floor plans and port-numbering schemes on site; the finished labels must match these exactly. Deliverables • Every CAT6 run properly routed, terminated, and certified • Patch panels dressed and connected to the mounted switches &bul...
