Need a clarification on capsman local forwarding

Mon Jan 23, 2017 10:15 am

From a little I've understood, to enable local forwarding I have to check "local forwarding" flag on capsman datapath config, and bind wlan and eth together with a bridge on each AP
Otherwise all traffic is controlled by manager
Am I right ?
What's the benefit in using a config rather than other and when they should be used ?

Thank you

Hi,
Consider this setup:

MikroTik gateway - CAPsMAN running --------------- AP ------------- DSL modem for some special connection



I have 2 subnets on main MikroTik gateway. Both MikroTik gateway and DSL modem have internet. But, I want to use DSL for some special needs.

I want to setup 3 different SSIDs for my subnets and another for DSL connection. All wireless configuration will be handled by CAPsMAN.

- First, for my subnets I create CAPsMAN forwarding configuration. CAPsMAN forwarding creates 2 virtual interfaces on main MikroTik gateway, those are basically your wireless interfaces on your AP. You don't need any configuration on AP. Using, configuration on CAPsMAN, you can add these virtual interfaces in any bridge you want. Just enable CAP on AP.
- Second, the third SSID for DSL is configured using local forwarding. This will not create any virtual interface on main gateway, but will just send configuration to AP. You need to setup all other necessary network configuration on AP yourself.

ok thanx for the explenation. i understand it and i tested it in my lab environment and is like this.
some questions...

1. so with capsman forwarding option the main router that holds capsman it will get more cpu busy. this apply when downloading from internet or when transfering files through lan? or both?
2. for a hotel hotspot (browsing,email,facebook etc) with 30 caps an rb2011 for capsman and 50mbps dsl speed, is it better capsman forwarding or local?

i like the capsman forwarding option because i can observe in capsman interfaces menu all virtual caps interfaces and what bandwidth they are upload/download. but if this is going to slow things down in my hotspots i better use local forwarding.

Hi,

1. Yes, I think it will apply to both. LAN transfer might use more cpu though.
2. In that case, I would use CAPsMAN forwarding. It is much simpler with CAPsMAN forwarding.
