He seems like a great consumer advocate and repair activist to me.

Haven’t gone more than 24 hours, if I had to guess maybe 20 hours.

So glad people are dipping out of plex.

I thought he was talking about amnesia the dark descent and the alien game combined, had no clue that game was a thing.

This looks like some type of bridge mode, which I don’t want. I want the vm to be isolated except for the jellyfin ports that are forwarded. I think nat mode and forwarding is the best if not only way to achieve this.

Well then your forwarding hook is broken and won’t work for the second VM.

Because of the lack of clarity, I assume you meant something was wrong with the elif statement, so I ditched that.

    /sbin/iptables -t nat -I PREROUTING -p tcp --dport $HOST_PORT2 -j DNAT --to $GUEST_IP:$GUEST_PORT2
   fi
fi
if [ "${1}" = "Nginx" ]; then

My goal is to isolate Jellyfin and nginx from my seeing network. I’m not following any guide that wasn’t linked in the post.

I want the VM so my system is more modular and secure.

Sorry! The ip was wrong, the nginx vm is 192.168.101.85. edited

We’re all gonna need to use whonix for basic shit now

I ended up just installing Alma Linux again. Thank you very much for your help.

DO NOT follow my lead, my backup solution is scuffed at best.

I have:

• RAID1 array w/ 2 drives
• Photos on the device that took them
• Photos on a random old hard drive pulled from an ancient apple mac.

I’ve got a hard drive and flash memory?

Don’t have this at all, the closest is that my phone is off-site half of the day.

yes, the host is 192.168.86.73 and it has that dnat rule.

And from the guest

Assuming you meant from the host, I am sshing directly to 192.168.101.4 instead of to 192.168.86.73:2222.

The third paragraph doesn’t make sense to me. I am using port 22 on my host(192.168.86.73) for it’s own ssh.

tcpdump returns this when I ssh to port 2222:

20:32:29.957942 IP (tos 0x10, ttl 64, id 28091, offset 0, flags [DF], proto TCP (6), length 60)
    192.168.86.23.53434 > 192.168.86.73.2222: Flags [S], cksum 0x5d75 (correct), seq 1900319834, win 64240, options [mss 1460,sackOK,TS val 3627223725 ecr 0,nop,wscale 7], length 0

192.168.101.4 is the alma guest. It’s got port 22 open and I can ssh into it from the host computer.

iptables -nvL on Alma returns:

Chain INPUT (policy ACCEPT 0 packets, 0 bytes)
 pkts bytes target     prot opt in     out     source               destination         

Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
 pkts bytes target     prot opt in     out     source               destination         

Chain OUTPUT (policy ACCEPT 0 packets, 0 bytes)
 pkts bytes target     prot opt in     out     source               destination         

I believe this means it automatically accepts connections.

IMO this makes it unlikely that the guest is the issue.

twitter is fucked and requires a login for everything, but reddit seems to work fine without a login.

ssh -v returns:

No firewalls on the client, but iptables on host and guest. guest has no rules just allow all, and host rules are listed in the post.

sysctl net.ipv4.ip_forward returns:

net.ipv4.ip_forward = 1

So I’m pretty sure that this is already enabled. Thanks for your answer!

From the iptables manpage:

--to offset
    Set the offset from which it starts looking for any matching. If not passed, default is the packet size. 

...

--to-destination ipaddr-ipaddr
    Address range to round-robin over. 

This seems to do something, but the port still appears as closed.

iptables -nvL returns:

After running the ssh command, the bytes seem to increase. After 1 ssh attempt:

After another ssh attempt:

No I tried to find the element before he shared this.
