Static IP's in the hotspot network bypass doesn't work.

RouterOS General
1

Using Version 2.9.8 of routerOS.
I have a hotspot running in a fairly large condominium. Within it there is the main office with two computers and 3 closed-box video recorders running a version of Linux (Dedicated micros). I want the office computers to be able to run a network viewer program that utilizes port 8234. I added the following entries which represent the 2 computers and 3 video recorders:
ip hotspot ip-binding add mac-address=00:D0:D9:02:FF:4C address=10.5.50.125 to-address=10.5.50.125 server=hs-local type=bypassed
ip hotspot ip-binding add mac-address=00:D0:D9:02:1F:2C address=10.5.50.126 to-address=10.5.50.126 server=hs-local type=bypassed
ip hotspot ip-binding add mac-address=00:D0:D9:03:7B:AF address=10.5.50.127 to-address=10.5.50.127 server=hs-local type=bypassed
ip hotspot ip-binding add mac-address=00:D0:D9:02:FF:4C address=10.5.50.150 to-address=10.5.50.150 server=hs-local type=bypassed
ip hotspot ip-binding add mac-address=00:0C:6E:46:DC:5D address=10.5.50.173 to-address=10.5.50.173 server=hs-local type=bypassed
The 2 pc’s which are at ip 150 & 173 can ping 125, 126, 127 but when we run the network viewer program it refuses to connect and when I open a command prompt and type “netstat” I see:

proto Local address foreign address state
TCP Harb_park:1250 10.5.50.125:8234 syn_sent

If I keep pressing enter, I may or may not finally get a connection. Its really hit and miss but once I get a connection, I can make it again over and over until some time passes and I try again. Also trying to use VNC (port 5900) between the two computers I get a “read: connection reset by peer” the first time I try and then it works the second time. It seems that the bypass doesn’t work correctly and that packets have to be sent between the two IPs before communication can be established. I also tried adding the ip/ports as bypassed in the walled garden/IP list but this doesn’t make any difference.

I use that box to get on the same subnet that the customers on hotspot are on so I can view the radios and ap’s as well. I have tried adding the walled garden ip list and also using the make binding in the hosts of hotspot with no success. Using 2.9.7 rb532 with alvarion and trangos behind the router
Anyone know?
thanks

Truzicka,
When you do your ping make sure that you are getting an arp from your video servers and not your MT.
the routerOS will respond to an arp on any ip you request one for. this makes it possible to have zero user ip configuration, static ips from a different subnet will still work with the hotspot.
If this turns out to be the problem, try changing the arp setting for the interface you have your hotspot on.
You are doing the bypass correctly we have 30+ of these boxes deployed all with hotspot bypasses working.

Ok so from the MT router console I enter
/ping 10.5.50.125 arp-interface=hotspot
and I get back
10.5.50.125 with hw-addr 00:D0:D9:02:FF:4C ping time=4 ms
10.5.50.125 with hw-addr 00:D0:D9:02:FF:4C ping time=3 ms
10.5.50.125 with hw-addr 00:D0:D9:02:FF:4C ping time=9 ms
10.5.50.125 with hw-addr 00:D0:D9:02:FF:4C ping time=4 ms
The MAC address is that of the video recorder I pinged

How does one disable the universal client and it really isn’t needed in this installation?

i think they just fixed your problem in 2.9.9

Just upgraded to 2.9.9 and low and behold all the devices on the bypass list are all reachable first try so looks like there was a bug.
