My setup:
modem / residential gateway (Cisco EPC3825)
|
router, openwrt chaos calmer (Linksys WRT1200AC)
|
lan (ethernet)
Ipv6 connectivity works perfectly if I plug my pc ethernet cable directly to modem. Also the openwrt router it self seems to have a perfectly working ipv6 connectivity. But once I plug pc ethernet cable to router ipv6 connectivity stops working.
