Very Strange issue has anyone seen anything like this? - XGS RED 60

I can't make sense of this issue,  any help / ideas would be much appreciated because i feel like I'm taking crazy pills <insert Mugatu>

I have the following setup:


XGS 2100  Site 1  (Latest Firmware)

SG 115  Site 2

The sites are connected via IPSEC and I have servers at both sites and I can transfer files and ping with no issues.

A RED 60 at the users home is connected to the XGS.  It can ping and browse / transfer files at site 1 and 2.   

If the user Pings anything at site 2 the RED drops and loses connection completely, I can see this in the VPN logs as RED disconnecting and reconnecting. 


TLDR:   Ping / ICMP Traffic to remote subnet causes RED to reboot but browse and file transfer works fine?!




Only thing I can think of is that the ISP has provided a /31 address.

Does anyone have an XGS with a /31 connection and is also using REDs?

  • This setup is new and the hardware RED 60 is new,  I replicated the issue with another new RED 60 so I don't think it's the RED hardware.   

    I was wondering if anyone has a firewall with a /31 subnet and connected REDs successfully?         (I have another site with an XGS firewall and RED's on a  /29 subnet with no issues.)   

    I'll have a look through the logs above and see what i can find.
