Hello,
Our company has been using a MikroTik RB1100AHx2 for several months. I didn’t configure it (that person has moved on), but I’m trying to learn it. We have two internet connections coming to our office. Right now we have a block of static IPs coming to the router from one modem (say ISP1). The modem is connected to the router on ether9. Everything on that side is configured fine, but today my boss asked me to obtain another block of static IPs on the other modem (say ISP2), to be connected on ether11. Each IP of ISP2 is to be NAT’d to a specific workstation in the LAN for web application testing purposes.
Most of the information I find on configuring dual WANs is regarding load balancing or failover, neither of which apply to me.
I know how to get a basic configuration up and running and I know routing basics. Here are some concerns:
- How to ensure that packets coming in through the ISP1 leave through ISP1’s gateway, and the same for ISP2? These are workstations that will use ISP1 for regular internet access, but will be accessed from the public internet through ISP2. Otherwise, all machines in the LAN should only access the internet with ISP1.
- Does anything special need to happen with NAT from ehter11 (ISP2) to access the specific machines?
Also, I’m more familiar with using Winbox than command line for configuration. Lame, I know.
Thank you in advance for your assistance.
