Finally, I found the solution to a nagging problem:
For some interfaces, I wasn't able to run natd -interface if0. It started
OK, but as the first packet arrived, it said
natd: Unknown interface name isp5. (Undefined error: 0)
The problem is in SetAliasAddressFromIfName(), where for the SIOCGIFCONF, =
a
buffer for only 32 entries is allocated:
struct ifreq buf[32];
While space for 32 addresses will suffice for a home setup with only two =
or
three interfaces and a limited number of addresses, I have three machines
with multiple ISDN connections which have up to 42 (sic!) interface
addresses assigned.
I would suggest to up this to at least 128 entries.
Alternatively, a method to dynamically size the buffer should be
implemented.=B4 If this is considered to be needed, I'll implement it.
Thanks,
Stefan
