|
- The next two changes affect config files:
|
|
- Add syn matching to acl.conf rules - this may break existing rules
|
|
- Add syn and port/protocol matching to forward.conf rules - this will not
|
|
break existing rules since it adds 4 new options at the end that can
|
|
be omitted completely.

=-=-=-=-= PRE 2.0 REWRITE =-=-=-=-=
|
|
1.1 - Brielle Bruns <bruns@2mbit.com>
|
|
- Reorder rules, place allow before block to allow overrides
|
|
- Fixes for conntrack rules for better security (added -o/-i)
|
|
- Correct some incorrect info in options.default
|
|
|
|
1.0 - Brielle Bruns <bruns@2mbit.com>
|
|
- Minor tweaks to various config files
|
|
- Fix issue with tweaks loading
|
|
- Version 1.0
|
|
|
|
0.9.14 - Brielle Bruns <bruns@2mbit.com>
|
|
- IPv6 DHCP bypass rules (IPV6_LANDHCPSERVER)
|
|
- Move FORWARD Established,Related rules to inside NAT rules, since without NAT,
|
|
we're not really going to need to track connections forwarding through the system.
|
|
I can probably be proven wrong if you don't use NAT but use the script for stateful
|
|
firewalling with non-RFC1918 IPs....
|
|
- Cleanup work on code for v1.0
|
|
|
|
0.9.13 - Brielle Bruns <bruns@2mbit.com>
|
|
- Fix location of ipv6 fi statement, moved to end of ipv6 rules
|
|
- Add default policy rules and IPV{4|6}_P{INPUT|OUTPUT|FORWARD} options
|
|
to control them. Note the difference between BLOCKINCOMING and the PINPUT variable
|
|
- Oops, looks like my state match of allowing NEW was undoing the incoming blocks. Fixed.
|
|
- IPV4_ALLOWED and IPV6_ALLOWED which will eventually replace TCPPORTS and UDPPORTS
|
|
|
|
0.9.12 - Brielle Bruns <bruns@2mbit.com>
|
|
- Change IPV6_ROUTEDCLIENTBLOCK so you can specify ranges to
|
|
block incoming to.
|
|
- Add support for allowing IPV6 critical ICMP messages, on by default
|
|
- Add support for interception of IPv4 packets, aka transparent proxy
|
|
- Add beginning support for error checking of variable inputs, still not functional yet.
|
|
- Test if we are using at least bash 3.x, since some of the more advanced features
|
|
we are using to make this script work don't work too well with bash < 3.0 or dash.
|
|
|
|
0.9.11 - Brielle Bruns <bruns@2mbit.com>
|
|
- Move some of the config clutter to conf/ - you can
|
|
put your config files anywhere, but by default, they're
|
|
now going to be in conf/
|
|
- Beginning work on configuration tool. If it ever
|
|
gets completed is a whole different story. :)
|
|
- Option to use state or conntrack module for state tracking.
|
|
By default, use conntrack.
|
|
- After some research, we seem to not need NEW state match in FORWARD
|
|
- Auto detect default gateway interface and IP of interface. Has potential problems
|
|
if run before we've got a default interface, so manually define EXTIF to be sure, and
|
|
things should be okay. This is mostly for people with dynamic IPs.
|
|
|
|
0.9.10 - Brielle Bruns <bruns@2mbit.com>
|
|
- Move clamp mss up earlier in the rules to possibly
|
|
fix an issue I noticed during testing
|
|
- Move icmp allow code
|
|
- Prevent duplicate icmp allow rules in NAT code
|
|
- NETMAP support in NAT code
|
|
|
|
0.9.9a - Brielle Bruns <bruns@2mbit.com>
|
|
- Minor bug fixes for my coding errors introduced in
|
|
the change of IPv6 variables
|
|
|
|
0.9.9 - Brielle Bruns <bruns@2mbit.com>
|
|
- Loadable module support during firewall loading
|
|
- More init script fixes.
|
|
- Non-conntracked DNS reply packets allow options
|
|
- Slightly improved IPv6 support to start to bring
|
|
it up to par with IPv4 support.
|
|
- ipv6 marking support, changed ipv4 to use | instead of :
|
|
- Renamed IPV6 variables, please read INSTALL file about conversion of config file
|
|
to new format.
|
|
|
|
0.9.8a - Brielle Bruns <bruns@2mbit.com>
|
|
- Fixing executable file permission issues
|
|
- Use /bin/bash in initscript cause dash does not recognize
|
|
more advanced methods that bash can use. Oops. Easiest
|
|
way to keep up to date is to symlink /etc/init.d/firewall-sosdg
|
|
to /etc/firewall-sosdg/doc/firewall-sosdg.init
|
|
|
|
0.9.8 - Brielle Bruns <bruns@2mbit.com>
|
|
- Almost at v1.0 quality for my tastes
|
|
- BLOCK_(INCOMING/OUTGOING)_RFC1918 options to help sure up security of LAN space leakage
|
|
- Changes to LANDHCPSERVER so it accepts interface names, plus a possible fix for win7
|
|
hammering DHCP server for unknown reason?
|
|
- Cleanups
|
|
- No longer display list of blocked IPs, considering if they are
|
|
as long as my list is, they'll take 4 pages to display...
|
|
- New block file format, much more capable now, thanks to
|
|
an hour or two of improving my bash scripting skills to the
|
|
point where I can do more complex breakdowns of formats
|
|
- Rename blocked to ipv4-blocked since we're going to have
|
|
ipv6 support
|
|
- ipv6 blocking support. Different format for config file
|
|
because IPv6 uses :, which means we get to use | for both
|
|
ipv4 and ipv6 (goes against a previous commit)
|
|
|
|
0.9.7 - Brielle Bruns <bruns@2mbit.com>
|
|
- Support for marking packets, uses new config file and
|
|
IPv4_MARK file option
|
|
- MULTI-NIC-ARP-LOCK hack added, to fix what I consider to be an annoying 'feature' of
|
|
arp requests on Linux
|
|
- Allow use of multiport iptables module to reduce amount of rules
|
|
|
|
