Hi,

I try to set up - A centos 6 firewall - With proxy-arp (I know: arp is not supported in ipv6) with ipv6.

Arp does not exist for ipv6. So I have added: sysctl -w net.ipv6.conf.default.proxy_ndp=1 To use the neighbor proxy facility.

How to activate ipv6 forwarding? As far as I have found, this changed in RHEL6 from 6.1 (/etc/sysconfig/network) to 6.2 (/etc/sysctl.conf). CentOS 6? So I have used sysctl -w net.ipv6.conf.all.forwarding=1 as in RHEL 6.2

As in ipv4 I would prefer to proxy the clients behind the firewall.

eth0 is WAN, eth1 is LAN.

I have read to use ip -6 neigh add proxy <ipv6 address of eth1> dev eth0 but ip -6 neigh show shows nothing.

Then I have tried Ip -6 neigh add proxy <ipv6 address of client> dev eth0 Same result.

Is there any How To for ipv6 routing and proxying for CentOS?

Best regards Helmut
