General Discussion / ipip6 tunnelling
« on: May 28, 2023, 05:03:26 pm »
Hi,
My ISP is providing ipv4 by tunneling it within a ipip6 tunnel.
I tried to establish such a tunnel using the opnsense GIF interface, however, I am not able to fill all the fields, as the remote ipv4 is not known.
Here is the linux equivalent setup:
Is it possible to achieve the same within opnsense ? (If necessary, i can use the CLI).

Code: [Select]
allow-hotplug ip4tnl0
auto ip4tnl0
iface ip4tnl0 inet tunnel
description wan4
address 82.64.11.22/32 # My public ipv4
mode ipip6
local 2a01:e0a:1111:2222:0:ffff:ffff:0 # My IPV6 address
endpoint 2a01:e00:29:200a::fffd # The relay
tunnel-physdev eth0.836
post-up ip -6 tunnel change ip4tnl0 encaplimit none
post-up sysctl -q net.ipv4.conf.ip4tnl0.forwarding=1
# Adds IPv4 default route to pass by this interface
post-up ip -4 route add default dev ip4tnl0
mtu 1500Is it possible to achieve the same within opnsense ? (If necessary, i can use the CLI).
