I get "Two or more interfaces found, checking IP forwarding [FAILED]" When I run "ipsec verify". I have tried adding <br><br>net.ipv4.conf.*.send_redirects=0<br>net.ipv4.conf.*.accept_redirects=0<br><br>for all my network interfaces and set net.ipv4.ip_forward = 1 but I still get the error message.
