You've told the interface that it can reach 10.227.148.52 via 10.234.37.80, which is the IP ue0 was configured to use. It sends ARPOP_REQUESTS to get the MAC address of 10.227.148.52 which is expected to be reachable. > Is any sysctl parameter can fix this problem? You can do things like use proxy-arp, or setup /etc/ethers, or NAT, or even configure ue0 to be on the same subnet as 10.227.148.52 instead, perhaps using an alias.
