34 is a read-only file which lists which IPSEC virtual interfaces are
35 attached to which real interfaces, through which packets will be
36 forwarded once processed by IPSEC.
39 Each line lists one ipsec I/F.
40 A table entry consists of:
43 an ipsec virtual I/F name
45 a visual and machine parsable separator '->', separating the virtual I/F
48 a physical I/F name, to which the ipsec virtual I/F is attached or NULL
49 if it is not attached,
55 the MTU of the ipsec virtual I/F,
57 the automatically adjusted effective MTU for PMTU discovery, in brackets,
59 a visual and machine parsable separator '->', separating the virtual I/F
60 MTU and the physical I/F MTU,
62 the MTU of the attached physical I/F.
65 <DT><B>ipsec2 -> eth3 mtu=16260(1443) -> 1500</B>
71 shows that virtual device
77 is connected to physical device
83 and that the effective MTU as a result of PMTU discovery has been
88 <DT><B>ipsec0 -> wvlan0 mtu=1400(16260) -> 1500</B>
94 shows that virtual device
100 is connected to physical device
106 and no PMTU packets have gotten far enough to bump down the effective MTU
107 from its default of 16260.
109 <DT><B>ipsec3 -> NULL mtu=0(0) -> 0</B>
115 shows that virtual device
118 is not connected to any physical device.
