Hi all main router- 3 static routes ip route 192.168.0.0/24 10.0.0.1 (routerA) ---- ip route 192.168.1.0/24 10.0.0.2 (routerB) ----same switch ---telecom company---client request ip route 192.168.2.0/24 10.0.0.3 (routerC) ---- Diagram ======= ---routerA--- main router ---switch ---routerB--- switch ---telecom company ---routerC--- dyname ip clients ip 192.168.0.0/24 and 192.168.1.0/24 static ip clients ip 192.168.2.0/24 This setting is fine when any dynamic ip clients sent from telcom company. But When telecom company sent request from static ip client (any ip in 192.168.8.0/22) but this client is sent to in routerA, how this work out? I really don't want to have 192.168.8.0 in routerC to routerB then routerA in loop as there will have big admin work if there is more than 3 routers and have increase new static ip client for the future Thank you for your help
