There is no option -P in RHEL8. You need to use the -w option followed by the argument sysctl -w net.ipv4.ip_forward=1 NOTE: No space before or after "=" sign.

you can view the system default line by "sysctl -a | grep ip_forward". "net.ipv4.ip_forward = 0" by system already has 'space' before/after '='. hence it is fine to have 'space'.

sysctl -w command cannot survive a reboot. hence others are suggesting to write a line into sysctl.conf. and followed by sysctl -p
