Instant remote serial console access for MSP and enterprise networks. No VPNs, no truck rolls — ConX-SFP works through NAT/CGNAT with outbound-only TLS.
ConX-SFP gives MSP, reseller, and enterprise operations teams a dependable way to reach customer consoles in minutes—no site VPNs, no truck rolls, no bespoke jump boxes.
Challenges this solves
- Break/fix incidents where the WAN is down but serial access is still required
- Volume provisioning across dozens of small sites with limited onsite skills
- Support contracts that demand audited access without granting LAN credentials
How it works
- Drop in: Insert ConX-SFP into any spare 1G SFP slot on the customer gateway, switch, or firewall—it presents just like a standard optic.
- Cable the console: Connect the supplied serial lead (single port or dual via breakout) to the device’s RS-232 console.
- Let it phone home: ConX-SFP acquires an IP via DHCP and establishes outbound TLS to the ConX Portal (cloud or on-prem).
- Click to connect: From the portal, launch a browser-based console session with per-user authentication and logging.
Why teams adopt it
- Works through NAT and CGNAT with no inbound rules to negotiate
- Ships preconfigured, so non-specialists can install it at the remote site
- Provides a uniform interface for routers, switches, firewalls, PDUs, and servers
Quick-start checklist (~5 minutes)
- Insert the ConX-SFP into any spare host cage.
- Cable the ConX-SFP serial lead to the target device (9600 8N1 by default).
- Verify DHCP assigned an address on the management VLAN.
- Open the portal and start the console session.
Tip: Air-gapped or regulated environments can use the ConX Portal in on-premises mode—no traffic ever leaves your network.
