PIX-501 DHCP Relay question

[DanielHaglund]

Hello.

Example set-up.
Internal net: xxx.xxx.xxx.0/28
PIX internal IP: xxx.xxx.xxx.1
PIX external IP: yyy.yyy.yyy.20
(Above addresses are public addresses, not private as 10, 172 or 192.)

If the PIX work as a DHCP-Relay and send the requests over a VPN-tunnel it sets the source address to yyy.yyy.yyy.20. Is it possible to set the source to the internal interface instead? (xxx.xxx.xxx.1)


General question, it's the internal interface that has DHCP Relay enabled, shouldn't the source be set to its IP?

Thanks in advance,
Daniel.
