The Startup Mode - DHCP with rapid fallback to static is global for eth0 and eth1. Therefore, if you configure the eth0/eth1 to DHCP, then eth1/eth0 is no longer in Startup Mode - DHCP with rapid fallback to static. Changing one to DHCP, automatically sets the other to DHCP, and similarly for Startup Mode. Both LAN and WAN interfaces must be changed so neither is in Startup Mode - DHCP with rapid fallback to static.
If you are only using a single Ethernet port (the LAN or WAN port, not both ports), and you are using a LON U60 interface with a static IP address for eth0 or eth1, then you must set the LAN Interface Gateway field for that port (LAN or WAN). For example, if you are using the LAN port, then set the unused port to Startup Mode (see the example below).
If you are using both the LAN and WAN port, then you need to assign the default gateway IP address only when needed. At least one default gateway IP address needs to be used (either assigned by DHCP or by manually adding to a static IP address). Assigning gateway IP addresses to both ports may cause issues with Ethernet communication. Some Ethernet communications will work properly and others may not.
