RouterBoard 750, Help needed.

RouterOS Beginner Basics
1

Hello,

I have this problem, that I can not resolve (I’m too green for in this staff).

so…
I have RouterBoard 750 with RouterOS v3.29 in office.
We have 2 different internet providers (“Online” and “Wanex”), I want to connect both of them in RB 750.
I’ve pluged Online in first interface and want it to come out in third one, Wanex into second and want it to come out in forth interface.

I also created 2 gateways (192.168.1.1 for Online and 192.168.1.65 for Wanex, both have there own DHCP servers), which are working properly.

also I’ve done this and I don’t know if this is correct.

so, what I want is to seperate 2 ISP in LAN with different gateways (users that are under 192.168.1.1 to use Online and under 192.168.1.65 - Wanex) and same time have 1 network, so that they can share files, if possible.

I will very greatfull if you help me, my job depends on it :frowning:
thanks

P.S.
sorry for my poor english.

P.P.S

You need policy routing. See: http://blog.butchevans.com/2008/09/mikrotik-policy-routing-implementation-example/ for a tutorial.

Butche,
thanks for reply.

the reason why I"m doing so is Load balancing, so did like this:
http://wiki.mikrotik.com/wiki/Load_Balancing_over_Multiple_Gateways

It worked, but now I’m having other problem, PCs are losing IP adresses after certein time, it’s not because of lease time (it is set on 365d 00.00.00). it wont work if I configure manually.
I think there’s something going on with DHCP Server:

#   NAME     INTERFACE     RELAY           ADDRESS-POOL     LEASE-TIME  ADD-ARP
 0   DHCP      Port3+Port4                       Pool                    52w1d         yes

Interface-Bridge

 0  R name="Port3+Port4" mtu=1500 l2mtu=1524 arp=enabled mac-address=00:0C:42:56:4D:8F protocol-mode=none priority=0x8000 auto-mac=yes 
      admin-mac=00:00:00:00:00:00 max-message-age=20s forward-delay=15s transmit-hold-count=6 ageing-time=5m
