Lines Matching refs:tunnel
81 - traceroute does not work. I planned to relay ICMP from tunnel,
99 (branches, that exceed pmtu are pruned) and tunnel mtu
125 /* Fallback tunnel: no source, no destination, no key, no options */
147 it will match only tunnel with the same key; if it is not present,
148 it will match only keyless tunnel.
151 will match fallback tunnel.
