Pf Beginner requesting help
I wasn't sure whether this topic would go under NAT, CARP, or MultiWan so here it goes. I have gone through countless pages and endless searching and, not that i havent seen a solution through searching, i somewhat dont understand it due to different setups etc. I am hoping this will be trivial for the experts out there so please advise this noob on how to set this up correctly.
At present i have:
1 /32 ip by ISP
block of 4 on /30 also provided by ISP.
I am currently running an ADSL modem on full-bridge mode and the pfsense box is handling the authentication via PPPoE. I have gone through several posts, and i am somewhat confused by the interchangable terms like 'using VLAN, Virtual IPs, CARP as opposed to ProxyARP, and 1:1;. Could somebody out there possibly provide me with some light as to how i could get these additional IPS operational.
Any help is much appreciated.
probably best if you put up a network diagram of what you are trying to implement. include the ip addresses , masks and gateway of everything.
Thank you for your reply Sai,
I roughly sketched up what i want to achieve out of the network, but if you have any suggestions that may improve this(because i think this design is very flawed), let me know. What i have done so far is ive managed to map the /30 ips by creating VLANS. What i want to do now is to be able to map those /30s to communicate with my /24 machines. Im not sure if that feasible or not for a /30 to point to a /24. Im confused as to how i should i approach this. Please provide me with some guidance.
Thanks in advance.
you dont need VLANS. http://en.wikipedia.org/wiki/VLAN
if you want to map your REAL ip addresses (on the /30) to your private ip addresses (on the /24) then you need NAT
so, if anyone on the internet tries to access your real ip he gets through to your server with a private ip ?
Let say that you have a.b.c.d as your WAN address. You want this to NAT to your mail server on 192.168.1.66 , so that when someone sends mail to you the mail server can handle it
Firewall: NAT: Port Forward
add a rule
External address: Interface address (if you want to add more IP addresses here you need to do this under Proxy ARP in the Firewall: Virtual IP Address menu)
External port range: the range of ports on the incoming packets (for mail that would be port 25 to port 25)
NAT IP: 192.168.1.66
Local port: 25
Description: SMTP packets to be sent to the mail server
now you need to add a firewall rule for this , which can be done by keeping the tick box next to "Auto-add a firewall rule to permit traffic through this NAT rule"
Thanks again for your reply Sai,
Ill give that a shot, then ill let you know.
Edit: Instead of manually creating entries for every port, is there a faster way to open all ports to an internal PC using this method? (DMZ)

Well you can define port ranges instead of single ports.
If you have multiple single ports you want to forward: use aliases
Thank you Sai and GruensFroeschli,
Your support has been much appreciated.
