On-call network architecture and troubleshooting

Senior network help without adding another full-time engineer.

WolfWarden provides focused architecture, troubleshooting, and security work for firewalls, routing, multi-ISP design, cloud connectivity, DNS, BGP, RPKI, and the difficult incidents that cross several systems.

$150/hour, two-hour minimum. Remote work in scheduled blocks, including outside business hours, with a written summary after each session.

Where the service fits

Bring the problem that does not fit neatly in one vendor ticket.

The highest-value network work often sits between the firewall, carrier, cloud, identity provider, DNS, and application team. WolfWarden works across those boundaries.

Architecture

Network and security design

Review current state, define decision criteria, document tradeoffs, and produce an implementation path that operators can support.

Firewalls

Policy, NAT, VPN, and segmentation

Troubleshoot flows, simplify rulebases, design resilient remote access, and separate zones without losing operational clarity.

Routing

Multi-ISP and BGP

Failover, path control, route policy, prefix filtering, max-prefix, session hardening, and the practical behavior carriers do not always document.

Cloud

Hybrid connectivity

Connect on-premises and cloud networks with clear routing, security boundaries, DNS behavior, and recovery expectations.

Routing security

RPKI and IRR

Create accurate ROAs, choose maxLength deliberately, align route objects, validate origins, and reduce the risk of hijacks and leaks.

Incident

Structured troubleshooting

Build a timeline, identify the actual failure domain, collect evidence, test hypotheses, and leave a written record rather than a pile of screenshots.

How engagements work

Focused blocks, not an open-ended retainer.

Start with two hours. Use the time to solve the immediate problem, validate a design, or create the next-step plan.

  • Before the sessionShare diagrams, symptoms, relevant configurations, constraints, and the decision you need to make.
  • During the sessionWork live through evidence, packet flow, routing state, policy, and vendor behavior.
  • After the sessionReceive a written summary of findings, decisions, commands or changes, and remaining risks.
  • Unused timeThe site currently states unused consulting time is refunded; confirm the exact block before purchase.

RPKI and route-origin validation

Signed authorizations, validated announcements.

Standard RPKI route-origin validation does not sign ordinary BGP updates. A Route Origin Authorization is the signed object that states which AS may originate routes for specific prefixes.

01

Prefix and ASN inventory

Document what is held, what is announced, which AS originates each prefix, and where records disagree.

02

ROA creation

Publish precise authorizations through the RIR portal with deliberate prefix length and maxLength choices.

03

IRR alignment

Bring route and route6 objects into line with the intended origin because many providers still build filters from IRR data.

04

Origin validation

Deploy relying-party validators, feed routers over RTR, and define policy for valid, unknown, and invalid routes.

05

Edge hardening

Max-prefix, customer filters, session protection, and change controls reduce the blast radius of leaks and mistakes.

06

External verification

Confirm the global view before and after changes so a locally correct configuration does not hide an invalid public state.

Good consulting inputs

Come with evidence, leave with decisions.

Good uses of a block

  • Intermittent routing or VPN failures
  • Architecture review before a migration
  • Multi-ISP design and failover testing
  • Firewall policy cleanup or segmentation plan
  • RPKI/IRR inventory and implementation
  • Vendor recommendation with explicit tradeoffs

May require a larger scope

  • Full 24x7 managed network operations
  • Large implementation projects with daily project management
  • Onsite cabling, hardware installation, or dispatch work
  • Unsupported platforms without safe access or documentation
