Since version 0.9, MoBlock no longer conflicts with other firewalls. Make sure
the following three conditions hold:
- MoBlock marks non-matched (IP is not in the blocklist)
packets. (The marking feature is on per default. It
will be explained and asked for later.)
- Other firewalls do not mark packets.
- MoBlock is started after other firewalls. If other
firewalls are started/reloaded after MoBlock, then you
need to restart MoBlock again. You will be fine, if the
iptables rules which send traffic to MoBlock's iptables
chains (moblock_in, moblock_out and moblock_fw) stand
before all other iptables rules which ACCEPT traffic.
You can check your iptables rules with
iptables -L -nv
