I configured my MikroTik in Bridge-mode and assigned two IP-addresses to the master interface (ether 2), e.g. 192.168.1.254 and 192.168.2.254. I now added one route that forwards all traffic to 188.144.0.0/16 to 192.168.2.99.
If I now traceroute from my client I receive
1: 192.168.1.254 (hurray!)
2. 192.168.1.212 (WTF???)
Question? Why on earth does the MikroTik route to 192.168.1.212??? Shouldn’t it just route to 192.168.2.99???
