Re: with money as no object, I need a real MT backhaul solution

To Promind: looking @ your answer, bonding seems to offer better performance than NStreme2, do you suggest to use it instead of NStreme2 ?

Rdgs
ofcourse, last several comments do say that. days after readings in this forum we replace nstreme2 with bonding in a backhaul... works better.

You can use 1 mt box for BGP with 1 ASN and more ISP.
You can use real IP for your client or nat.
1st MT box is attached @ isp1, 2nd - @ isp2. both routers have attached customers on it.

hi there!
you can find many posts onto the forum with that treatement. but i think that you have a porblem related to cables, antennas, etc. signal levels <if they perpetual, ofcourse> are quite enought to pass 30Mbps of traffic. we have similar link tx/rx=72/72 with 25Mbps full duplex.

in general, you should not break the VLAN and bridge it with other interfaces. i think, on router1, you should add vlanid=333 on interface connected to router2, bridge both vlan interfaces. then do it on router2/3. and then you can limit traffic on different interfaces on router2 =) is that meant t...

Disabling any static routes and firewall rules does not resolve the issue. All routes are dynamically created routes. WAN IP is gathered from DHCP and DHCP adds default route, dynamically. WAN IP: a.a.a.a WAN gateway: a.a.a.b LAN IP: 192.168.1.1 Looks like this: 0.0.0.0/0 routes to a.a.a.b a.a.a.0/...
