Thanks Lonnie
No my modem just bridges the IPoE to Astlinux and gives it a default gateway.
The modem itself is on 172.30.254.2/24 and usually 172.30.254.1 is configured
on eth0 with PPPoE as the WAN interface.
This is now not configured on eth0 but it should be able to be added as a
secondary address I assume?

Hi Michael,
Are you saying the ISP is providing both DHCP and Static IPs for your
public WAN address(es) using the same routed subnet?
My business DOCSIS cable modem ISP provides either a DHCP or a Static IP
public WAN address, but not both at the same time for the same interface.
Basically because the DHCP addresses are routed in a different public subnet
versus the Static addresses.
On the other hand, if only DHCP is used for the public WAN address, then to
admin your bridge modem using a static private address should work without any
extra effort.
Again in my example, the cable modem will accept HTTPS connections to
192.168.100.1, provided 192.168.100.1 is routed via the default route over the
WAN path, the modem's web interface will appear. Though if you defined a local
private 192.168.100.1/24 LAN network or block RFC1918 egress traffic, the
modem's web interface will be blocked.
