It keeps calling pf_map_addr(), trying to get a new IP to c= heck for available ports. I believe this problem was introduced by the patch in PR# 184003. Note that we're running NAT with PF_POOL_STICKYADDR, so we find a src_node,= and the early return is taken. This means we always return the same IP, and loop through the available ports in pf_get_sport() again and again. This loop continues until a state times out, and we do find a free port. --=20 You are receiving this mail because: You are the assignee for the bug.=
