4. Serial Port, Host, Device and User Conﬁguration

4.11.3 IP Passthrough Conﬁguration

To conﬁgure IP passthrough:

• Click Serial & Network: IP Passthrough and check Enable.

• Select the Modem to use for upstream connectivity.

• Optionally, enter the MAC Address of downstream router’s connected interface.

Note: If the MAC address is not speciﬁed, the console server will pass through to the ﬁrst downstream device requesting a DHCP address.

• Select the Ethernet Interface to use for connectivity to the downstream router.

• Click Apply.

4.11.4 Service Intercepts

These allow the console server to continue to provide services for out-of-band management when in IP passthrough mode.

Connections to the modem address on the speciﬁed intercept port(s) will be handled by the console server, rather than being

passed through to the downstream router.

• For the required service of HTTP, HTTPS or SSH, check Enable.

• Optionally modify the Intercept Port to an alternate port (e.g. 8443 for HTTPS). This is useful if you want to continue to

allow the downstream router to remain accessible via its regular port.

4.11.5 IP Passthrough Status

Refresh the page to view the Status section. It displays the modem’s External IP Address being passed through, the

Internal MAC Address of the downstream router (only populated when the downstream router accepts the DHCP lease), and

the overall running status of the IP passthrough service.

Additionally, you may be alerted to the failover status of the downstream router by conﬁguring a Routed Data Usage Check

under Alerts & Logging: Auto-Response.
