For V2.2, parts of the linux kernel have
been re-written in order to support
'xfrm interfaces' that enable route-based IPsec. Route-based
IPsec offers
IP interfaces as tunnel end-points that can be handled by the normal
routing
table and by routing protocols.
The control software for the WWAN modules has been completely
re-written
in order to support new and future WWAN modules without affecting the
operation of the existing and older WWAN modules in the field. Also
support
for Dual-SIM versions and external (MuLogic) WWAN modems has been added.
The SNMP agent has been extended with several OIDs for the managment of
WWAN modems and connections.
With the introduction of Version 2.2, a new version numbering scheme is
used.
Where for versions 2.0 and 2.1 the format was <mayor version
number>.
<minor version number>-<build number> like 2.1-4398, with
the change to
using Git instead of SVN as version control system, the format now is
<mayor version number>.<minor version number>.<revision
number>
like 2.2.0, which is the first release.
RSA-series SNMP
MIB file
The MIB file is now added to the firmware and can be downloaded via the Management>Access
services>SNMP page of the unit's web interface.
Note:
After loading new firmware, it may be neccesary to reload the page
in the web
browser in order to update
the html content that is stored in the web browser's
cache. If the unit's web interface remains in the web
browser's cache then new
menu items may not be displayed.
