I am fiddling with a FreeBSD + Webmin setup, upgraded to today. The IPFilter settings "establish" okay, but after turning on the ipf rules, and re-entering the ipfilter screen in webmin, I get this instead:
error parsing IPF line block in quick on re0 inet from 192.168.0.0/16 to any at inet line 2 : remainder inet from 192.168.0.0/16 to any
Makes no difference as to what line 2 is, I can put anything there, and it still breaks the parser.
The ipf.rules file to line 2 is:
# Skip next rule for external interface
skip 1 in quick on re0 all
# Allow all traffic on internal interface
pass in quick all keep state
# Block some never allowed traffic
block in quick on re0 from 192.168.0.0/16 to any #RFC 1918 private IP
Firewall itself is working fine, the blocks are blocking etc. Just can't see them in Webmin. I know FreeBSD 10.1 isn't supported (yet?) but figured if you decided to work on it, you would need to know this.
