That's what I suggested them. But since they were already running servers on IPs from both the subnets, we have to either put the box in bridge mode or create IF Aliases. As of now it's running fine and may be due to cable or switch problem errors are being shown in Interface statistics. Thanks & regards, Nishant thats a widely used techniqe for routing purposes. so the isp can change the routing quickly and apply more subnets to that route. you can use one and the same router for many subnets than. the /29 is the routing subnet and the /28 your official subnet. so there should no need for arp'ing. Just put the /28 on an DMZ NIC and the /29 on WAN. The first free IP of the /28 may be supposed to be the NIC IP of the DMZ. Everything should be fine than? = = = http://michael-schuh.net/ = = = Projektmanagement - IT-Consulting - Professional Services IT Rev. P.D.

I had already configured it with configuring one subnet on WAN and adding rest of the IPs as IF Alias. Everything is working fine. More interesting thing that I saw was, which ever subnet or gateway you use, traffic was always going through the gateway for /29 subnet. regards, Nishant On Thursday 13 June 2013 11:39 PM, Adam Thompson wrote: > This case sounds tailor-made for transparent mode, to me. > -Adam > > Alex Threlfall <[email protected]> wrote: > >> My money would be Proxy Arp'ing them - but I might also consider going Media >> Convertor > 4 Port Mini Switch > WAN1 (/28) and WAN2 (/29) interfaces. >> There's probably a more elegant way of doing this tho. >> >> -- >> Alex Threlfall >> Cyberprog New Media >> www.cyberprog.net >> >> >>> -----Original Message----- >>> From: [email protected] [mailto:list- >>> [email protected]] On Behalf Of Nishant Sharma >>> Sent: 09 June 2013 14:11 >>> To: pfSense support and discussion >>> Subject: [pfSense] Two Subnets on WAN >>> >>> Hi, >>> >>> Here is a deployment scenario where ISP has provided two subnets - /29 >>> and /28. >>> >>> There are already servers running on public IPs from both the subnets and >> I >>> have to put pfSense in front of them.
