Good morning,
I have disabled forseencaps and enabled IPv6. I can establish a VPN
connection via IPv6. But no traffic goes through. IPv4 connection is
working.
I'm sharing my config below. I would really appreciate it if somebody could
help me with that.
*/etc/sysctl.conf*
net.ipv4.ip_forward = 1
net.ipv4.ip_no_pmtu_disc = 1
net.ipv4.conf.all.rp_filter = 1
net.ipv4.conf.all.accept_redirects = 0
net.ipv4.conf.all.send_redirects = 0
net.ipv6.conf.all.forwarding = 1
*/etc/strongswan.d/charon/socket-default.conf*

}
