I use netfilter-persistent to manage a firewall.



I would like to share a connection between two interfaces using masquerading (example, or another). When I run those operations by invoking iptables it works.



But if I try to update firewall rules stored in /etc/iptables/rules.v4 adding such a line: 



-t nat -A POSTROUTING -o wlan0 -j MASQUERADE


Lines starting with -t make netfilter-persistent fail to run and the firewall is not updated:



Nov 16 11:51:32 helena systemd[1]: netfilter-persistent.service: Main process exited, code=exited, status=1/FAILURE
Nov 16 11:51:32 helena systemd[1]: Failed to start netfilter persistent configuration.


So I am wondering if it is possible to store this kind of rules with netfilter-persistent or



  • Is it a known limitation?

  • Is there a good reason why it cannot work?

  • Is there a hack to make it work?

          How many registers does an x86_64 CPU actually have?

          Image
          Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this
