I hope I am doing something really stupid after a long day!!!
I have a very simple setup that I know I have had working before. BUT… low and behold… I can’t get it going now!!
ok… Basically I have a ProxMox host. On this host I have a single NIC. I have created to Virtual interfaces. one is “public” facing (RE: on my internal LAN) and the other is PRIVATE… no routing or anything just a subnet to run on the host only.
I have a Gateway VM on the box… with 2 NIC’s. One on the LAN and one on the Private subnet. ON this box I have install Tailscale. connected, authorised etc. all good. I have enabled subnet-routing through the --advertise-subnet argument etc… modded the appropriate sys files etc. now… I can PING the said VM on both interfaces from my laptop. So it appears TS is working. I can then, through this VM, ping other hosts on the Private subnet, but this is where I run into problems… I can ping but not connect otherwise. One of these private boxes is a straight up linux box, so am trying to SSH in. If I am on the GW VM I can SSH to the said box, but not from my laptop which is on the LAN side of the network…
please tell me I am missing something dumb?? my brain hurts!!
Thanks in Advance
