Hi there,
I'm trying to limit the bandwidth usage for the CIFS Protocol (445) between our different locations using QoS. We connect our locations through a RED tunnel, each one has an own LAN.
Why we need it:
We have on our central a 100M/100M internet connection, on one of our locations (call it Site1) we do have just 20M/20M, if we copy a file over UNC path from/to the site the whole bandwidth will be used and the site won't have enough bandwidth to use other services.
Interface configuration on Site1:
(All the interfaces have Limit uplink, Limit Downlink and Upload optimizer activated)
eht0: Local-LAN 192.168.15.0/24 - QoS Status on - 1024M/1024M
eth1: WAN-Connection Default GW - QoS Status on - 20M/20M
eth2 & eth3: have different local networks that need internet, they don't have anything
redc4: RED tunnel to the central 10.168.0.2/30 - QoS Status on - 20M/20M
Traffic selector configuration:
Source: 192.168.15.0/24
Service: CIFS(445)
Destination: Any
TOS/DSCP: Off
Bandwidth pool:
Bound to interface: eth0 (Local-LAN)
Bandwidth: 128kbit/s
Limit: 5120kbit/s
Traffic selector: "CIFS From Local-LAN to Any"
What I've tried:
I've also tried to bound the Bandwidth pool to the redc4 interface, but it doesn't work either. If I run "iftop -i eth0" or "iftop -i redc4" I see the connection between the to computers over the port 445, with "iftop -i eth1" I only see the connection through port 3400 (i suppose it's the RED tunnel), so I've discarded the possibility to bind the bandwidth pool on the WAN interface.
I think I don't really understand how it works maybe it isn't even possible to do what a want to do, do you have any tips on how to do this? I hope there is enough information to understand what I want to achieve and how our system is configured.
Best regards,
Alberto.
