in shorewall.conf. This is done to ensure that "shorewall refresh" will
|
||||
work correctly.
|
||||
|
||||
6) Shorewall now supports UDP IPP2P matching. In addition to the "ipp2p"
|
||||
keyword in the PROTOCOL column of the relevant files, the following
|
||||
values may be specified:
|
||||
|
||||
ipp2p:tcp Equivalent to ipp2p and matches TCP traffic
|
||||
only.
|
||||
ipp2p:udp Matches UDP traffic.
|
||||
ipp2p:all Matches both UDP and TCP traffic. You may
|
||||
not specify a SOURCE PORT with this PROTOCOL.
|
||||
|
||||
Migration Considerations:
|
||||
|
||||
1) The "monitor" command has been eliminated.
