Network administration help for firewalls, VPN, routing and infrastructure access

Professional network administration for businesses that need expert help with firewalls, VPN, routing, switching and access control — without maintaining a full-time network engineer on staff.

We configure, troubleshoot and maintain network infrastructure across a range of platforms and vendors.

Platforms and equipment

What we cover

Cisco routers and switches

• IOS basic and intermediate configuration
• Access Control Lists (ACLs) — standard, extended, named
• VLAN configuration, trunking, inter-VLAN routing
• Static and dynamic routing (OSPF basics)
• Port security, DHCP snooping, storm control
• Interface troubleshooting, link aggregation

Brocade / Ruckus switches

• ICX series switch configuration and management
• VDX fabric switches — basic administration
• VLAN and trunking configuration
• Basic SAN switching (Fibre Channel zoning fundamentals)
• Firmware management and maintenance

MikroTik

• RouterOS configuration and management
• Firewall rules, filter chains, NAT
• VPN — IPsec, L2TP, SSTP, WireGuard
• Routing — static routes, OSPF, BGP basics
• Queue management, bandwidth control
• Hotspot and CAPsMAN basics

Firewalls

• pfSense and OPNsense — rules, NAT, VPN, HA basics
• Firewall rule design and access policies
• NAT — port forwarding, 1:1 NAT, outbound rules
• Stateful inspection, connection tracking

VPN

• Site-to-site IPsec tunnels
• Remote access VPN (OpenVPN, WireGuard, L2TP/IPsec)
• Split tunneling, routing through VPN
• VPN troubleshooting — phase 1/2 failures, MTU issues, NAT traversal

General network operations

• VLAN planning and implementation
• Routing between locations — static routes, OSPF basics
• DNS troubleshooting — resolution, forwarding, split DNS
• IP address management and subnet planning
• Access policies and network segmentation
• Network documentation and topology mapping

Common tasks we handle

• VPN not connecting — diagnosing phase failures, certificate issues, routing problems
• Firewall blocking traffic — rule analysis, logging, corrective changes
• Server unreachable — tracing path, checking routes, ACLs, NAT
• DNS resolving wrong or not at all — forwarder issues, zone problems
• Routing between office locations — tunnel setup, route tables
• IP restrictions — limiting access to specific sources, geo-blocking
• VLAN advice — segmentation design, trunk configuration
• Emergency remote access restore — recovering management access after lockout

Important notes on network changes

Network changes carry inherent risk. Our approach:

• All changes are planned with rollback procedures documented before execution
• We test in stages where possible and verify connectivity after each change
• Some changes may require out-of-band access (console, IPMI/iLO/iDRAC) as a safety net
• We will advise if a change requires physical access or scheduled maintenance window

How it works

1. Describe your network issue or requirement via contact form
2. We assess the environment, request access details and confirm the plan
3. Changes are executed with rollback preparation
4. You receive documentation of what was changed and verification results
