pix501, port redirecting, aliases

Aug 29, 2006 2 Replies

Hello


---publicIP--pix501----LAN (192.168.1.x)



I want to put VoIP Gateway into LAN, but with IP addres 10.10.10.111.


  1. Is it posibble with pix501 to have 2 networks on LAN ? alias command ?
  2. I have to redirect some ports to this gateway (eg. UDP 16384) - how to do this in this case ?

regards

No, you have to do it like this:

---publicIP---pix501---LAN(192.168.1.x)---Router---VoIP(10.10.10.111)

You don't need a real router - a cheap routing switch will do.

access-list out_to_in permit udp any(1) interface outside eq 16384 route inside 10.10.10.0 255.255.255.0 192.168.1.Y(2) static (inside,outside) udp interface 16384 10.10.10.111 16384 netmask

255.255.255.255 access-group out_to_in in interface outside

(1) = Do not use 'any' if you know the needed IPs (2) = The IP address of the new router
