Tnx Steve. I used the monowall shaping wizard to set up initial traffic
shaping. That gives me 2 pipes and 8 queues:
1 900 Kbit/s m_Total Upload
2 15200 Kbit/s m_Total Download
1 m_Total Upload 50 m_High Priority #1 Upload
2 m_Total Upload 30 m_High Priority #2 Upload
3 m_Total Upload 15 m_High Priority #3 Upload
4 m_Total Upload 4 m_Bulk Upload
5 m_Total Upload 1 m_Hated Upload
6 m_Total Download 30 m_Bulk Download
7 m_Total Download 10 m_Hated Download
8 m_Total Download 60 m_High Priority Download
To give my VoIP device (a FritzBox 7270 handling POTS and DECT) as much
as possible precedence over all other traffic, I added a two rules
(there already many rules, mostly p2p stuff forced in low prio queues).
IF PROTO Source Dest Target
WAN * 192.168.10.100 * m_High Priority #1 Upload
WAN * * 192.168.10.100 m_High Priority Download
Might be narrowed down to udp and even the VoIP server I'm always
talking to. Is this the right way to give an IP number precedence for
all its traffic?
I hope formatting stays a bit as I designed it...
