Hardware is RouterBoard R/S 433AH, Internet account with Charter Communications using a Motorola SB5101N SURFboard cable modem.
The R/S 433AH has software Ver 4.11.
ethernet port 1 WAN main router IP gets public IP address from Charter Communications
ethernet port 2 DHCP to router routing through ethernet port 1
ethernet port 3 private IP address to use with WINBOX for configuration
I can’t communicate with Charter DNS server. Pinged the remote host no response.
Should I do DCHP relay?
