I have 2 routers, same model and firmware, with both having openvpn servers auto start mode upon router power up. 1 router has optware and transmission software installed. Second router mainly usage is for openvpn server mode. To save electricty and prevent damage to connected harddisk while not in use from using 1st router. I would power up 2nd router and power down 1st router. At that moment, I notice that I lost connectivity on 1st router, cant access lan web unless I turned off 2nd router.
Both openvpn uses different TAP/TCP port numbers and both have same wireless ethernet bridge connection mode to DHCP router (netgear wndr3300).
Does it mean that only 1 openvpn server router exist in a given common subnet?
