23.7 Legacy Series / Virtual IP / IP Alias question

« on: December 21, 2023, 09:10:17 am »

Hi!
I have added an IP Alias to my WAN interface (PPPoE configured and up), because I am using a DSL modem that is connected to the WAN interface which has a management GUI. I want to access this management GUI (on 192.168.178.1) via the IP Alias I want to configure.
Now my problem is, after adding the IP Alias I don't see this IP anywhere. Neither in my ARP table or my routing table, nor with ipconfig. Further, I cant reach my router's LAN IP when loggen on to ssh on my opensense fw.

Layout is:
Internet --- Router --- <opensense wan interface PPPoE + IP alias> --- Opensense --- <lan interface with VLAN trunk> --- Core switch

Am I configuring it wrong? Can anyone give guidance?
Thank you :-)

Found this: https://github.com/opnsense/plugins/pull/3321
But it does not appear in the addons list (community)
This would be a perfect solution for my use case

Yeah, I am just connected via OpenVPN - thats why I am concerned to break the interenet connection. No way back if so :-)

Wow! thank you for the instant reply!
Is there any way to have OPNsense revert to the config before the change if not approved in a period of time?
(Just looking for a self repair...)

23.7 Legacy Series / Virtual IP on WAN (PPPoE)

Hi all,
I have my internet connection on a WAN interface with PPPoE configuration. My modem is a FritzBox in Modem only mode, connected via Ethernet. Everything works fine but I would like to be able to connect to the mamangement GUI of my FritzBox router. This means I need an IP address in the router's management LAN on my WAN interface. Can I simply add a virtual IP on the WAN interface to achieve this or would this interrupt/break my PPPoE internet connection?
I assume no, because currently my WAN interface only talks PPPoE and with adding a virtual IP address I just all IP to that interface, right? I just must not break the default GW of my OPNsense.
(Sitting remote, hence I could not fix it if I break it...)
Thank you for any thoughts!
