Hey All, Hoping someone can lend a hand here. I have ~ 1k customers running GRE tunnels back to me for VoIP. Over the last three weeks these tunnels have started to break at a rate of 3-5 per day. We've narrowed it down to customers using specific Spectrum routers (rac2v1s and rac2v2s). I am still able to access the public IP but the tunnel drops and will not come back up. The fix has been to reconfigure as VPN or have the CPE router replaced with a rac2v1k. I have been unable to get anyone to listen to me at Spectrum as these accounts are owned by the customer and I can't prove a systemic issue. I have a list of accounts that have been impacted. Has anyone else encountered this? Any contacts at Spectrum that might listen to me? I am fearing all of these tunnels will go down at some point. Thanks, Chris
