Inside my recv() function I do like this without problems:
// clone the current packet and change some fields
Packet* new_p = clone_pkt(p);
hdr_ip *new_iph = hdr_ip::access(new_p);
new_iph->daddr() = ...;
new_iph->saddr() = addr();
// change fields on the current packet
iph->daddr() = id2iaddr(th->b_id);
iph->saddr() = addr();
// send original packet somewhere
send(p, 0);
// send cloned packet elsewhere
send(new_p, 0);
