RouterOS Wireless Networking
1

Hello everybody,

I have a problem with my pppoe wireless clients,they cant open some URLs, like Hotmail, batanga and the MSN. It was working good. this is my conf.
RB153, In Eth1 = pppoe in order to connect with my ADSL. eth2= go out with utp cable to a RB530 in my tower.
rb153 (eth1) = PPPoE client
(eth2)=192.168.2.1 nat 192.168.2.0,
RB500(eth1)=192.168.2.2 gtw 192.168.2.1
(wlan1)=192.168.100.254

The client get a ip from WLAN1 of the rb500, with pppoe they cant open the pages, but with hotspot they can.
I have already changed the mss, but neither can.
Thanks for helping me i need achieve that, the customers got angry with me¡¡¡¡¡

Sounds like an MTU issue. I set mine to 1400 althought I see a lot of people say to set it at 1420.

Yep, MTU makes sense
