Re: very slow RB1100AHx2

We just placed 3 RB1100AHx2,s running 5.14 on our fiber based core LAN (with 10/100/1000 media converters in front of each) and then to a 4th x2 running 5.14 as the core router on a gigabit Metro Optical Ethernet circuit (200mbps active). COre router to an x2 at the other end of the MOE get's 199mbps. Any of the 3 x2 thru the core to the other side also 199mbps.

The 3 x2 are doing simple masquerade of 10.0.0.0/8 to the public IP on the default route. 450gs through out our network CANNOT do a UDP bandwidth test to the core x2. Result is zero. Existing Aastra 6730; VOIP phones will not place outgoing calls through the x2's doing NAT. Grandstream ATAs will not register on ports 500/5061. Change ports to 5012 and they register.

Further, customer speed tests to the distant side of the MOE yield terribly slow results.

We replaced one x2 with a 450g running 5.14 and everything that was broken is fixed. We are now going to replace the other two x2's that are natting with 450Gs running 5.14 to see what happens...

Is ANYBODY else having issues with the x2's at 5.14????
