I’m bringing in an external expert to tighten up a mixed-vendor environment that spans Cisco, Juniper, HPE/Aruba switching and a FortiGate firewall. Most of the day-to-day items run well, yet lingering issues around VLAN design, trunk consistency, OSPF versus static routes, and a few NAT quirks at the edge are starting to show. The single highest-value task is establishing a reliable Site-to-Site VPN between two offices so we can retire an aging MPLS circuit. Beyond that, I’d like you to review current firewall rules, clean up redundant objects, and confirm that inter-VLAN routing on the switch stacks lines up with our security zones. SolarWinds is in place for monitoring; if you see gaps in SNMP polling or alerting, feel free to tune those as you go. To keep expectations c...

Our VMware Cloud Foundation 9 deployment is ready for its management-domain build and I need the underlying network finished off quickly and cleanly. The hosts sit on Aruba switches, and the remaining tasks centre on switchport updates, IP/DNS adjustments, and a complete firewall rollout so the VCF bring-up checks pass first time. Work to be completed • Aruba switchports: create or modify trunks/access ports, tag the correct VLANs for Management, vMotion, vSAN, NSX-Edge and future workload domains, then document every change. • IP addressing: finalise the allocation plan, reserve management ranges and update any DHCP scopes. • DNS: add the A/PTR records for SDDC Manager, vCenter, ESXi, NSX and support services so name resolution works end-to-end. • Firewall: im...
