سلام
من 2 خط اینترنت دارم میخوام بریزم رو هم. بعد بدمش سوئیچ
میشه لطفا راهنمایی

دوست عزیز به این کار میگن لودبالانس . باید با روتر این کار رو انجام بدید . یا با دستگاه لودبالانسر . عبارت لودبالاسن رو سرچ کنید آموزشش در انجمن هست
البته بعضی از شرکت ها واسه fail tolerance تحمل خطا این کار رو میکنن.از دو خط همزمان استفاده میکنند
سلام
باید از میکروتیک استفاده کرد و بعد بزنیم میکروتیک رو به سوئیچ؟ چه روتر بوردی رو باید بخریم؟
غیر از میکروتیک با چی میشه این کار رو کرد؟
اسم این کار در نهایت لود بالانس است یا کلاسترینگ؟
از میکروتیک 750 استفاده کنید دو خط wan رو میزنی به میکروتیک و یکی خط میره سوئیچ. تو انجمن یک سرچ بزن load balancing mikrotik قبلا بحث شده عزیز
Load Balancing over Multiple Gateways
The typical situation where you got one router and want to connect to two ISPs:
Of course, you want to do load balancing! There are several ways how to do it. Depending on the particular situation, you may find one best suited for you.
Policy Routing based on Client IP Address
If you have a number of hosts, you may group them by IP addresses. Then, depending on the source IP address, send the traffic out through Gateway #1 or #2. This is not really the best approach, giving you perfect load balancing, but it's easy to implement, and gives you some control too.
Let us assume we use for our workstations IP addresses from network 192.168.100.0/24. The IP addresses are assigned as follows:
- 192.168.100.1-127 are used for Group A workstations
- 192.168.100.128-253 are used for Group B workstations
- 192.168.100.254 is used for the router.
All workstations have IP configuration with the IP address from the relevant group, they all have network mask 255.255.255.0, and 192.168.100.254 is the default gateway for them. We will talk about DNS servers later.
Now, when we have workstations divided into groups, we can refer to them using subnet addressing:
- Group A is 192.168.100.0/25, i.e., addresses 192.168.100.0-127
- Group B is 192.168.100.128/25, i.e., addresses 192.168.100.128-255
If you do not understand this, take the TCP/IP Basics course, or, look for some resources about subnetting on the Internet! We need to add two IP Firewall Mangle rules to mark the packets originated from Group A or Group B workstations.
For Group A, specify
- Chain prerouting and Src. Address 192.168.100.0/25
- Action mark routing and New Routing Mark GroupA.
It is a good practice to add a comment as well. Your mangle rules might be interesting for someone else and for yourself as well after some time.
For Group B, specify
- Chain prerouting and Src. Address 192.168.100.128/25
- Action mark routing and New Routing Mark GroupB
All IP traffic coming from workstations is marked with the routing marks GroupA or GroupB. We can use these marks in the routing table.
Next, we should specify two default routes (destination 0.0.0.0/0) with appropriate routing marks and gateways:
This thing is not going to work, unless you do masquerading for your LAN! The simplest way to do it is by adding one NAT rule for Src. Address 192.168.100.0/24 and Action masquerade:
Test the setup by tracing the route to some IP address on the Internet!
From a workstation of Group A, it should go like this:
C:\>tracert -d 8.8.8.8 Tracing route to 8.8.8.8 over a maximum of 30 hops 1 2 ms 2 ms 2 ms 192.168.100.254 2 10 ms 4 ms 3 ms 10.1.0.1 ... From a workstation of Group B, it should go like this:
C:\>tracert -d 8.8.8.8 Tracing route to 8.8.8.8 over a maximum of 30 hops 1 2 ms 2 ms 2 ms 192.168.100.254 2 10 ms 4 ms 3 ms 10.5.8.1 ... You can specify the DNS server for workstations quite freely, just make it can be reached (test it by tracing the route to DNS server's IP address)!
