I don't know much about the Ubiquiti stuff (we use Radwin) but i'd try
to use routing as much as possible in conjunction with a decent routing
protocol (OSPF, etc) and ip helper-address (or local DHCP in every
remote). When using bridging, you're carrying broadcasts everywhere,
not to mention potential loop / delay problems if you're not using
spanning tree. It's all a matter of getting the information about what
you want to achieve and what are the needs:
- End to end QoS (if you're doing VoIP, etc)
- Redundancy (Links, routers, branch access, Internet access, etc)
- Performance and monitoring (SNMP/RMON, SLA, etc)
- Remote access
With all these infos, we can come up with a design that will match the
needs and choose the right stuff.
As for the comment about Cisco Vs mOnOwall (better performance), you
compare oranges and apples. Cisco has products that are able to route
multi-gigabit so no problem with performance whatsoever... I use and
respect a lot mOnOwall for what it is but it is an entry level
solution. Cisco supports much more protocols and has enterprise
features mOnOwall can't match. That being said, mOnOwall may be able to
do the job and be a great bargain for SOHO shops. It all depends on
your needs as stated above.
