Hi, It seems as the flowtable acceleration doesnt support sending ipv4 traffic via an ipv6 next-hop. At least when i have tried i see the device running the flowtable sending arp requests for IP addresses that should be routed. If i add ipv4 next hop addresses then the flowtable works fine. The use case is having the netfilter firewall also running FRR with BGP unnumbered to minimize IPv4 address allocation for link networks and with flowtable acceleration to make it faster :) Cheers,
