Raw message 

Hi Tim,

 

i use a WRT54GL with DD-WRT (AP mode, no encryption, IP: 10.1.0.2 /
255.255.255.0, GW+DNS 10.1.0.1, DHCP of and forward to 10.1.0.1) directly
connected to squid.

Client WLAN connection to the WRT54GL works fine.

 

The repeater is an edimax EW-7438RPn (IP: 10.1.0.8 / 255.255.255.0, GW:
10.1.0.1)

http://www.edimax.us/html/english/products/EW-7438RPn.htm

 

the repeater is connected to wrt54gl and I got a dhcp lease from grase
server.

I cannot ping the grase server and got timeout.

 

Lars

Hi Lars

Firstly, what equipment are you using?

Currently your access points and repeaters must only be doing Layer 2
routing. Layer 3 should be left to the hotspot. This means you shouldn't
need DHCP relays, and your access points and repeaters IP's shouldn't be on
the grase network (mostly for security, but also so they don't interfer with
a client). They should be setup as "ethernet bridges", with all Layer 3 (IP
addresses and such) handled by grase.

The best way to think of it, is they should be setup transparently like an
ethernet switch. You don't know how many ethernet switches are between you
and a server, just how many routers. If you can tell how many wireless
devices are between you and the server (due to IP routing instead of
Ethernet routing) then they are setup wrong.

Let us know what model equipment you have, and the settings in them.

I´m testing grase since some weeks and all works fine.

I´ve found some help for the squid logging problem in the mailing list but
now i´ve a problem to connect a repeater.

 

This is my configuration:

Grase Server:

- IP 10.1.0.1 / 255.255.255.0

- DHCPStart 10

- DHCPend 250

 

WRT54GL AccessPoint-1

- IP 10.1.0.2 / 255.255.255.0

- GW / DNS: 10.1.0.1

- DHCP forwarder: 10.1.0.1

- no encryption

 

WRT54GL AccessPoint-2:

- IP 10.1.0.3 / 255.255.255.0

- GW / DNS: 10.1.0.1

- DHCP forwarder: 10.1.0.1

- no encryption

 

Now I want to connect a repeater to AccessPoint-2.

 

Repeater-1:

- 10.1.0.8 / 255.255.255.0

- GW: 10.1.0.1

- no encryption

 

Repeater-1 is connected to AccessPoint-2, dhcp works fine, but I can´t reach
the grase server / internet

If I ping the grase server 10.1.0.1 I get a timeout. Ping to Accesspoint-1
and Accesspoint-2 works fine.

 

Please give me a hint what i´m doing wrong.

 

Thx

 

Lars
