Hi, if you have 192.168.1.x on one side and 192.168.0.x on the other, why did you bridge between these Networks? Just use the SXTs as router on each side between both, so you don't need any filter.

Hello,

I think MT is a serious solution, but sometimes restricted to the Linux. If you need more in some special situations, e. g. a PPPoE-Server for more than roundabout 500 concurrent user, you may take a specialized solution for this topic, and not a full featured RouterOS System.

Regards

It make sense to use NStreme if you want to connect so much customer to an AP in an outdoor PtMP installation, so you would not run into the "Hidden Station Problem" which kill lot of 802.11 traffic. A CPE on RB/411 base is also very cheap and have support for all the stuff a WISP need. Re...

1. Check if your ISP provide MLPPP

2. If not, take a second MT system in a datacenter and make an EoIP-Tunnel to that system across each uplink. Than you can bond the EoIP-Interfaces on both sides to one pipe. For this, all uplinks should have the same speed.

solution is simple and straigt forward, just use public IPs, thats it. We offer in Germany a tunnel connection to our central systems with an EoIP or L2TP tunnel, so our customers can get public ips thru that tunnel.

Can you please provide the IP config of the AC and the pool you use.
