My home network already runs on pfSense, but I need an experienced hand to tune it properly. The immediate priorities are: • Firewall rules – I want clear, maintainable rules that explicitly allow only the traffic I specify while leaving everything else untouched. • WireGuard VPN – configure the tunnel, keys, and routing so that remote devices can reach the LAN securely. • Traffic shaping – optimise bandwidth usage and prioritise latency-sensitive traffic. Everything should be implemented directly in the pfSense GUI, with inline comments or descriptive labels so I can understand and adjust settings later. I’ll provide current backups and remote access to the dashboard for the session. At the end I expect an updated config file plus a short chang...

I already have a Contabo server standing by and simply need a clean, production-ready ViciDial stack on it. The job covers: • Installing the latest stable ViciDial (with Asterisk and its dependencies) from scratch. • Optimising the underlying Linux distro you feel is most reliable for call-centre workloads. • Hardening the box with a well-tested firewall configuration—CSF, UFW, iptables, or a similar solution is fine—as long as only the ports Vicidial, SSH and web administration actually require remain open. • Verifying that the web interface, database, and telephony services all start automatically after a reboot and that calls can be placed through a demo campaign. • Supplying a concise hand-off sheet: all commands run, credentials created, a...

I already have a functioning codebase that reaches Amazon endpoints, but I now need to harden and streamline the network layer. The top priority is Optimized Proxy Deployment: spinning up several proxy servers on AWS, each tied to its own Elastic IP and placed in regions nearest to the Amazon infrastructure we query. The target footprint is roughly 100 static IPs—half reserved for one domain and half kept in a common pool. Every outbound call must rotate to the next address so no two consecutive requests share the same IP, keeping average round-trip latency between 150 ms and 300 ms. When Amazon responds with a 429, the system should swap both the IP and candidateId instantly, with zero observable delay to the application. A second goal is lowering the overhead around our creat...

I am preparing for the CompTIA Security+ certification and want targeted, exam-style tutoring that zeroes in on Network Security—specifically firewalls and VPNs. The goal is to master the current exam objectives, clear up any conceptual gaps, and build enough confidence to score well on test day. Sessions should be live, interactive, and paced to my schedule. I learn best when theory is tied directly to hands-on examples, so walking through real-world firewall rules, VPN configurations, and related packet-flow scenarios is essential. Explanations must stay aligned with the Security+ wording and depth so I recognize the phrasing when it appears on the exam. Deliverables: • A structured lesson plan broken into manageable milestones • Live tutoring sessions with screen-sha...

Hi I will share the details with the shortlisted candidates. Thanks

This project covers the end-to-end creation of a brand-new Local Area Network for our premises. The environment will serve daily operations for both computers and servers as well as our shared printers and scanners, so stability, speed, and clean segmentation matter. The scope begins with planning: assessing the floor layout, sizing the switch stack, deciding on cable runs, and selecting hardware that fits future growth. Layer-2 and Layer-3 configuration must follow best practices—think VLAN separation for user groups, QoS where printing traffic needs it, and a security baseline that shuts unused ports, enforces 802.1X, and applies sensible ACLs at the edge. During implementation, I expect neat rack work, labelled cabling, and documented configurations (Cisco-style CLI or equivalen...

I have several Cisco-based lab and production environments that need hands-on attention from someone who already feels at home with CCNA-level work. Over the next few weeks I’ll be refining network configuration, tightening security, and—most importantly—sorting out a few stubborn routing-protocol issues that keep popping up. Here’s the situation: • Network configuration needs polishing on a mix of Catalyst switches and ISR routers, including VLAN planning, trunking, and interface tuning. • Day-to-day troubleshooting consumes far too much time; I want clear root-cause analysis when links flap, routes disappear, or access lists misbehave. • Security hardening is overdue—standard ACLs are in place, but I need smarter filtering and a quick r...

I need help installing routers for a series of small communication-network rollouts. Each day’s route will be planned in advance, and the actual on-site work rarely exceeds one to two hours. Your role is straightforward: pick up the assigned router, travel to the client location, mount the unit, connect it to the existing cabling, confirm internet connectivity, then send me a quick photo and speed-test screenshot before leaving. The schedule is flexible as long as the job is finished on the agreed day; I issue payment weekly, starting at 25 000 ₽, and increase it for consistently smooth, on-time work. What matters most to me is punctuality—I’d rather reschedule than keep a client waiting—and complete honesty about any delays or technical issues you encounter. Basi...

I have a WebRTC soft-phone built with JsSIP that needs to register to an Asterisk 18 server over WSS. SIP credentials are confirmed correct, yet the browser console shows an authentication failure. The signalling path is protected with TLS certificates, so the problem is somewhere in the certificate handling or the way Asterisk presents the challenge. Your job is to trace and eliminate the registration failure, then hand back a clean configuration and proof that the client can successfully register and place a test call. Environment details you will touch: – Asterisk 18 (pjsip stack enabled) – JsSIP running in a standard browser (wss://) – TLS with server and client certificates already issued Acceptance criteria: • JsSIP completes REGISTER without 401/403 r...
