Firewall Jobs

I already have a Linux server online and reachable; what I need now is a clean installation and full configuration of Asterisk, FreePBX, and A2Billing so I can run a reliable business phone system. Your scope covers: • Installing the latest stable releases of Asterisk, FreePBX, and A2Billing on my existing server • Bringing the stack to a “ready-to-use” state—SIP extensions, VoIP trunks, IVR, call recording, voicemail, and billing profiles must all function out of the box • Hardening the server (firewall rules, Fail2Ban, strong passwords/keys, SSL where applicable) • Running test calls to confirm inbound and outbound traffic, rate decks, CDR logging, and balance deductions in A2Billing • Handing over a concise post-deployment guide so I ...

I need someone based in Russia who can walk me through, and if required remotely execute, the full setup of a VPS that will physically reside on Russian soil. My priority is simply getting the server online and production-ready; once it is running smoothly I will maintain it myself. We will start by choosing a reliable Russian provider, spinning up the VPS, and installing the usual stack (Linux + either Nginx or Apache, plus SSL, firewall hardening and basic monitoring). You will also take care of the initial configuration so the site loads over its domain the moment I point the DNS. Russian-specific compliance requirements, if any, should be covered as part of the setup. Deliverables • Active Russian-based VPS with root access handed over • Web server, SSL, firewall an...

Over the past few days I have noticed a sharp, unexplained spike in direct traffic on my corporate website. The pattern is the same worldwide—thousands of repeated page views hitting the same endpoints every few minutes—yet no genuine engagement follows. Because I have no firewall, captcha, or other security layer in place, I suspect an automated script or bot is hammering the site and inflating my analytics. I need a security-minded developer to: • Analyse server logs, analytics data, and DNS records to confirm the source, volume, and behaviour of the suspicious requests. • Pinpoint whether the traffic originates from a compromised script inside the site, a third-party resource, or external botnets. • Recommend and implement practical counter-measures such...

I have just opened a brand-new Leaseweb account and want to make sure everything is configured correctly before I begin hosting production workloads. At this stage nothing has been provisioned, so I need someone who knows their way around the Leaseweb control panel to walk me through the complete setup, spin up the first server, apply sensible security hardening, and leave me with clear notes on what was done and why. Typical touch-points will include picking the right plan, deploying an instance, setting up user access, SSH / RDP configuration, firewall rules, monitoring basics, and any tweaks you consider best practice for performance and reliability. I’m open to either Windows or Linux images, so your recommendation here will be welcome. The job is primarily about the initial se...
