Hello and thank you in advanced for any advice. Our current setup is a /30 WAN and a /25 LAN handoff from the ISP. Our device is the SSG-350 and have configured the /30 for external and the /25 mapped (mip) to some private ip addresses. Our issues started when our traffic increased over the holiday season that the sessions table filled up a couple of times last month.
We purchased a pair of SRX1500 which will run alongside this setup, with a new upstream from a different provider. With the old SSG still in place, is it possible to forward one of its /25 ip's into this new SRX, without the SSG tracking the session, so in effect just behaving like a plain router?
