<antaresgades>
Hello!!! I have a dual NIC setup, LTSP server in 192.168.2.1, internet at say 178.23.5.x. From the server i am able to ping both to internet, the 178.x. net and also the 192.168 net.
10:50
But from the client, i am not able to ping the internet, just the 178.x net and also 192.168 net.
10:50
You can see route and configuration details here https://pastebin.com/qNVhjyWG
10:50
I guess I've something messed up with routes, but can't solve by myself
10:51
<alkisg>
ltsp automatically does ip forwarding and nat when ip=192.168.67.1
10:51
For 192.168.2.1, you would need to do it manually
10:53
<antaresgades>
I've did it in the past for sure, because I installed some months ago LTSP and it went very well... but can't recall how I did it.
10:58
I think the steps are something like touching sometinh it sysctl.conf related to ip forwarding and also messing a little with iptables. any suggestion on search terms to find some light?
11:00
<alkisg>
grep -r MASQ /usr/share/ltsp
11:00
See the ltsp code, and do something similar
11:05
<antaresgades>
Yes, I tried that with a slightly different syntax (what I found elsewhere) and doesn't work, but just with that line it works!!! Thanks!!! And to make that persistent, I guess the best option is to modify the file where that sentence is written, isn't it?
11:15
ok, looks like installing iptables-persistent under ubuntu 20.04 solves the problem, thanks!!!!
11:18
<alkisg>
Put it in POST_SERVICE_x in ltsp.conf
11:25
<antaresgades>
thanks!!
