Title: My WAN IP keeps dropping
Post by: lowfuriouysISP on June 06, 2026, 12:35:52 AM
Hello everyone, im new to Opnsense. I have recently set up my Dell Optiplex as my opnsense box, I have a Intel x550-T2 dual Nic 10GbE as my wan and lan ports. I have a netgear CAX30 on bridged mode acting as my modem. Also my ISP is Cox. The setup works fine for the first 10 minutes then it drops both IPv4 and IPv6 public addresses, then it comes back in 2 minutes and it just keeps looping. So my workoaround was to set it up as double NAT, but of course it's not ideal. Any suggestions would be really helpful.

Thanks :)
