Router OS 3.17

load-balance working very well butt disconnect my messengers after every 10 to 15 minutes and automatic reconnect
yahoo, msn messengers or some software's

My Configuration


/ ip firewall nat
add chain=srcnat out-interface=wan1 action=masquerade
add chain=srcnat out-interface=wan2 action=masquerade

/ ip firewall mangle
add chain=input in-interface=wan1 action=mark-connection new-connection-mark=wan1_conn
add chain=input in-interface=wan2 action=mark-connection new-connection-mark=wan2_conn
add chain=output connection-mark=wan1_conn action=mark-routing new-routing-mark=to_wan1
add chain=output connection-mark=wan2_conn action=mark-routing new-routing-mark=to_wan2

/ ip route
add dst-address=0.0.0.0/0 gateway=192.168.20.254 routing-mark=to_wan1
add dst-address=0.0.0.0/0 gateway=192.168.10.254 routing-mark=to_wan2
add dst-address=0.0.0.0/0 gateway=192.168.20.254,192.168.10.254 check-gateway=ping

where my mistake?
plz tell me
Thanks

where's your load-balance configuration?..

where's your load-balance configuration?..

i already wright Load Balance configuration if its not good or wrong plz tell me, plz check again

just ECMP routing? =)

what is your tcp-established timeout in Connection tracking?

p.s. ECMP is not good for messengers, imho...

plz give me good script for Load Balance
i check already wiki but its not work properly

Thanks

sorry i am bigner, you meens /ip firewall conections /tracking ?

ther is default setings

try http://wiki.mikrotik.com/wiki/Load_Balancing_Persistent

try http://wiki.mikrotik.com/wiki/Load_Balancing_Persistent

that is my Configuration

add dst-address=0.0.0.0/0 gateway=192.168.20.254,192.168.10.254 check-gateway=ping

that is on wiki site (http://wiki.mikrotik.com/wiki/Load_Balancing_Persistent)

/ ip route
add dst-address=0.0.0.0/0 gateway=10.111.0.1,10.112.0.1 check-gateway=ping

add dst-address=0.0.0.0/0 gateway=10.111.0.2 routing-mark=to_wla2

not a big difference with my configuration or wiki site
but its not working properly
plz give me other configuration script or any other idia?
thanks

I have a similar problem. Absolutely correct konfig and result as for you, one time a precipice goes per 10-15 minutes.

For me a hope is on more stable version of Mikrotika or more correct rules of Load Balancing.

sorrrry, wrong link... can't find right example... there was something like http://wiki.mikrotik.com/wiki/Load_Bala ... e_Gateways , but based on dynamic address-lists (with 'Nth' client gateway selection algorithm)...

maybe someone could help?..

Later:

Oh, I found it =) It was erased in older version of that page =( Try http://wiki.mikrotik.com/index.php?titl ... oldid=5656

p.s. Who's Megis?.. Janis, is that you?.. Why no comments on that edit? Was that functionality built in RouterOS? Or it was always there, and using address-lists changes nothing, just complicates the setup?..

Thanks Chupaka
i try that link http://wiki.mikrotik.com/index.php?titl ... oldid=5656
that is work on Router OS 2.9.+ , but when i try in 3.17 or 3.22 and give this comand
'''/ ip firewall nat'''
add chain=srcnat connection-mark=odd action=src-nat to-addresses=10.111.0.2 \
to-ports=0-65535
add chain=srcnat connection-mark=even action=src-nat to-addresses=10.112.0.2 \
to-ports=0-65535
router give me 1 error, assign port udp or tcp
and when i assign port tcp, is working butt problam same messenger disconect after few minuts

any other idia?

Your src-nat rule will not function with udp traffic as presently composed. While don't you remove the to-ports and protocol. This will make sure that all traffic make with either even or odd connection marks go through the right interface irrespective of their protocol.

ip firewall nat
add action=src-nat chain=srcnat comment="" connection-mark=odd disabled=no to-addresses=10.111.0.2
add action=src-nat chain=srcnat comment="" connection-mark=even disabled=no to-addresses=10.112.0.2

yep, in v3 you shouldn't use 'to-ports'

when i assign port's tcp, is working butt problam same messenger disconect after few minuts

i need some more help!!!!!!!!!!!!!!!!!
thanks

Remove "to-ports" and protocol=tcp from your src-nat rules! Read my earlier post above.

mangle mesengger port than mark routing and make marking route from mesengger to one gateway..

You can try it. let us know the result.

1. ip address
add address=192.168.0.1/24 interface=LAN
add address=202.191.124.200/28 interface=wlan1
add address=202.191.127.162/28 interface=wlan2

2. ip firewall mangle
add chain=prerouting src-address-list=odd in-interface=LAN action=mark-connection
new-connection-mark=odd passthrough=yes
add chain=prerouting src-address-list=odd in-interface=LAN action=mark-routing
new-routing-mark=odd passthrough=no
add chain=prerouting src-address-list=even in-interface=LAN action=mark-connection
new-connection-mark=even passthrough=yes
add chain=prerouting src-address-list=even in-interface=LAN action=mark-routing

add chain=prerouting in-interface=LAN connection-state=new nth=2,1

3. ip firewall nat
add chain=srcnat out-interface=wlan1 action=masquerade
add chain=srcnat out-interface=wlan2 action=masquerade

4. ip route
add dst-address=0.0.0.0/0 gateway=202.191.124.193 routing-mark=odd
