  • As far as I am concerned, the ifcfg-ppp0 file should have the line `ETH="enp4s0.6"` in it. Also I recommended starting without `LINUX_PLUGIN="/usr/lib64/pppd/2.4.5/"` until you have it working. An MTU of 1508 seems high. I know with ADSL that you normally limit it to 1492 or less. Having said that, it is irrelevant if you have the `LINUX_PLUGIN="/usr/lib64/pppd/2.4.5/"` line as it gets ignored (which is why you need the extra firewall rule).

    You can try packet sniffing with tcpdump bit I am not sure you you'd packet sniff after your switch. You would be looking for a difference in the packets.
