Hotspot + Bridging

RouterOS General
1

Hi guys

I have a Mikrotik Server with 3 LAN card:

LAN (hotspot installed)
WAN1
WAN2

I have some webserver on LAN which is connected through a wireless link, how do I make a bridge only for that specific web server’s mac to WAN1 which I have my S-DSL modem connected to?

I tried the normal bridging but my hotspot stopped working.

some config sample is highly appreciated.

thanks

I assume you have to use full NAT. Leave private address on your servers, but add public addresses to WAN interface, and set NAT rules

actually no,
I want a fully transparent bridging only for specificied mac address,
meaning I not want to translate the address to local address where
my web and mail server is running.
the reason is, if I give the local address (for example range of 10.x.x.x)
the control panel software has difficulty to understand its public address
and will drop certain request on http request…

any idea on how to do bridging?

thanks for the reply.

no one ever done briding in addition of hotspot?

my webserver is down for so long, please help

bridge two interfaces and add some rules to broute table (/interface bridge broute)

Everything that is dropped from broute table will be routed.

Problem with that is:

  • All my ARP record will indicate > INVALID
  • All my hotspot servers will indicate > INVALID
  • The whole network will jam after I bridge the network in such way,

Any idea why is that so?

You have to be more specific on your network layout and problem description.

8

here it how it looks,
hope it is clear to understand.

Have you considered giving this web server a separate vlan, that could be later bridged with the WAN interface?

of course.
but the problem is my webserver is located on different location which on my managed switch i had to link it to LAN port of my gateway.

any help on the briding tricks?

11

the question is after I did the bridging, should I set hotspot to LAN interface or Bridge interface?

how about IP settings? should be assigned to bridge interface or lan interface?

thanks

12

can anyone at least give me a broute example?
the documentation is very poor and has no sample setup at all.

do I need two bridge for both interface?
if assign two interface to one bridge, then which interface
I shoud assign my WAN ip and LAN Ip? and which interface
I must assign to hotspot?

thanks

ok guys,
Here is the following setting that I could achieve the bridging I want to…

/ interface bridge 
add name="bridge" mtu=1500 arp=enabled stp=yes priority=32768 ageing-time=5m \
    forward-delay=15s garbage-collection-interval=5s hello-time=2s \
    max-message-age=20s comment="" disabled=no 
/ interface bridge port 
add interface=LAN bridge=bridge priority=128 path-cost=10 comment="" \
    disabled=no 
add interface=WAN2 bridge=bridge priority=128 path-cost=10 comment="" \
    disabled=no 
/ interface bridge broute 
add chain=brouting in-interface=WAN2 \
    src-mac-address=00:00:00:00:00:10/FF:FF:FF:FF:FF:FF \
    dst-mac-address=00:00:00:00:00:00/00:00:00:00:00:00 action=accept \
    comment="" disabled=no 
add chain=brouting in-interface=LAN \
    src-mac-address=00:02:3F:19:B3:0F/FF:FF:FF:FF:FF:FF \
    dst-mac-address=00:00:00:00:00:00/00:00:00:00:00:00 action=accept \
    comment="" disabled=no 
add chain=brouting dst-mac-address=00:0C:42:06:0C:E3/FF:FF:FF:FF:FF:FF \
    action=accept comment="" disabled=no 
add chain=brouting src-mac-address=00:00:00:00:00:00/00:00:00:00:00:00 \
    dst-mac-address=00:0C:42:06:0C:E1/FF:FF:FF:FF:FF:FF action=accept \
    comment="" disabled=no 
add chain=brouting mac-protocol=arp action=accept comment="" disabled=no 
add chain=brouting action=drop comment="drop everything else" disabled=no

any idea how to fix invalid hotspot?

thanks
