[lwip-devel] [bug #33634] ip_forward() have a faulty behaviour.

[hanhui]

Follow-up Comment #12, bug #33634 (project lwip):

OK, My English may not be clearly, that do discard bcast/mcast SYN is just a
example of M_CAST flag, but BSD use ip and link-layer address together to
determine bcast/mcast SYN, the BSD code as follow:

if (m->m_flags & (M_BCAST|M_MCAST) ||
    IN_MULTICAST(ntohl(ti->ti_dst.s_addr)))
    goto drop;

but you can temporarily not add this flag. It does not matter now. 

Thanks!
