Looking for guidance on pf and aliases. I have an OBSD 3.8 box running
pf in front of two SMTP servers.
Here's my setup:
Net -> 1.2.3.4---------> pf box -> box1 9.8.7.6
1.2.3.5 (alias)-> -> box2 9.8.7.7
Problem is, pf sends all requests to box1, even those addressed to 1.2.3.5.
Here are the relevant bits from pf.conf:
ExtIf=xl1
ExtIfa="1.2.3.5"
IntIf=xl0
box1="9.8.7.6"
box2="9.8.7.7"
nat on $ExtIf from $IntIf:network to any -> ($ExtIf)
rdr on $ExtIfa inet proto tcp from any to $ExtIfa port 25 -> $box2
rdr on $ExtIf inet proto tcp from any to $ExtIf port 25 -> $box1
pass in quick on $ExtIfa proto tcp from any to $box2 \
port 25 flags S/SA keep state
pass in quick on $ExtIf proto tcp from any to $box1 \
port 25 flags S/SA keep state
Again, I'm looking to get requests to two public addresses mapped to two
private addresses. Right now, everything goes to the box1.
Thanks in advance for clues on this.
