I have a MikroTik 5009B that needs to leave our lab ready for long-term production use under our brand. The job covers every layer of configuration—network setup, routing, security hardening, firewall rules, and wireless optimisation—so the unit ships with best-practice performance and rock-solid protection. Alongside the technical build I also want it re-branded: a custom RouterOS build that shows our logo on boot, a web interface reskinned in our colours, and a repeatable set of configuration scripts that already include our company name, contact banner, and standard VLAN/DHCP scheme. I should be able to flash a new device in minutes and have it come up with the same look, feel, and settings you create here. Deliverables • Complete live configuration on the 5009B, fu...
I’m spinning up a new enterprise deployment of Omnissa / VMware Workspace ONE and need a senior engineer who can own the entire UEM lifecycle from architecture through steady-state support. The environment spans Windows, iOS, Android and macOS devices, so you must be equally comfortable writing custom profiles for iOS as you are managing Windows patch rings or Android Work Profiles. Beyond the core console work, deep integration with the following is critical: • AD, Exchange, PKI, certificates, VPN High-availability design, DMZ and firewall rule-sets, unified application cataloguing, device enrollment flows, compliance policies and large-scale production rollouts all fall inside the scope. You will document everything you build and walk my internal admins through the solu...
My office network has become painfully sluggish and I need a specialist to jump in, trace the bottleneck and restore normal speeds. This is a pure troubleshooting engagement—no fresh installs or routine maintenance—so I’m expecting systematic diagnostics, clear root-cause identification and a fix that holds. The issue: noticeable performance degradation that shows up as slow internet speed for all users. Basic resets and router reboots have not helped, so I suspect something deeper (mis-configured switch, bandwidth hog, firmware bug, or similar). Here’s what I need from you: • Remote or on-site diagnostics using your preferred tools (Wireshark, NetFlow analyzers, SNMP monitoring, etc.) • Actionable remediation—configuration tweaks, hardware recom...

My site has suddenly stopped loading and I’m pretty sure it’s a DNS-related problem. I haven’t knowingly made any recent changes, though I’m not 100 % certain. The good news is that I can log into the hosting control panel, so you’ll have full access to DNS zones, nameserver settings, and any server logs you might need. I have a rough idea of how the records should look, but I’m not confident enough to troubleshoot this myself. Here’s what I need from you: • Inspect the current nameserver and DNS record configuration (A, CNAME, MX, AAAA, etc.). • Identify and correct any mis-pointed or missing records so the domain resolves properly worldwide. • Confirm propagation and show that the site loads over both HTTP and HTTPS from multi...
I’m refreshing our on-premises network and want it configured and stress-tested by someone who lives and breathes both infrastructure and security. First, the infrastructure work: • Build out the Layer-2 and Layer-3 design—router and switch configuration, IP addressing, VLAN segmentation, and DHCP where required. • Ensure the new topology is clean and resilient, with clear change notes so I can reproduce or roll back any step. • Troubleshoot anything that crops up during the cut-over and document the fixes. Once the cables are tidy and the configs committed, I’ll need you to put on the black hat—legally, of course. Using tools such as Nmap, Nessus, Kali Linux, or your preferred equivalents, perform network scanning, a full vulnerability assessment, ...

I’m ready to launch a new social-networking web application and need a solid technical foundation first. Your main focus will be designing and configuring the complete network environment that will host the platform—router and switch selection, VLAN design, firewall rules, VPN access, redundancy strategy, and clear diagrams so the setup can be replicated or scaled later. Once the backbone is defined, we’ll move straight into the web application itself. I want a browser-based social network built with a modern, well-documented stack; feel free to recommend React, Vue, Node.js, Django, or whatever you’re most efficient with, as long as it is secure, modular, and future-proof. Core features include user registration/login, profile management, friend/follow mechanics...
I need a ASA specialist to jump on a screen-share with me and tidy up two Cisco ASA 5512 units that are managed through ASDM. The primary goal is to enhance security, so every change we make should follow best-practice hardening guidelines.

Printing from my ERP POS breaks down whenever the tablet tries to reach the network; the job never even reaches the printer. The connection itself seems fine, yet the tablet is hit with permission errors at the network layer. I suspect a mis-configured network permission that blocks the tablet’s traffic to the POS service. Here’s what I need: • Pinpoint why network-level permissions are refusing the tablet’s requests. • Adjust the router, firewall, VLAN or Wi-Fi ACLs so the tablet can reach the ERP POS endpoint without drops. • Validate that receipts print reliably from the tablet afterward. You may use any packet-capture or remote-diagnostic tools you like—Wireshark, nmap, router logs, ERP POS diagnostics—so long as the result is clear: the t...

I’m running a Fortigate 400E on firmware v7.2.12 (Build 1761). An IPsec tunnel is already in place for Android handsets and is performing flawlessly, but our iPhone users still can’t connect. I’d like you to create the corresponding IPsec profile, test it on current iOS versions and provide concise deployment instructions for end-users. I don’t have special demands on cipher suites or authentication beyond Fortinet’s defaults, yet I’m open to your best-practice advice. Likewise, I’m undecided about split-tunnelling: please explain the pros and cons in our environment and apply the option you recommend. Once connected, users should enjoy full access to the internal network exactly as our Android profile allows. Deliverables • Fortigate CLI ...
My small business runs entirely through a MikroTik-based network, and over the past few days something has gone wrong. Connections drop at random and performance is far from normal. I have ruled out the ISP, so the problem appears to be somewhere in the current router or switch configuration. You’ll receive full remote access to the MikroTik router and, if necessary, winbox/terminal credentials for the rest of the network gear. The task focuses purely on troubleshooting: pin-point the fault, correct it, and make sure the fix survives a reboot. If during the process you identify mis-configured firewall rules or routing loops, feel free to tidy them up, but the priority is to get the network reliably online again. Deliverables • Diagnosis summary outlining root cause • ...
