Did Verizon DSL (East coast / USA) change VPN practices or filtering today?
We have 4 site-to-site IPSec VPN tunnels up all the time, and today our tunnel to a Verizon DSL endpoint (ASA-5505) will not connect! This is very frustrating. Of course Verizon does not "support" VPN tunneling on their DSL, but it has worked fine in the past. Nothing changed in any configs. Other 3 VPNs are working fine, but none of the other endpoints are Verizon.
The VPN structure is ASA to ASA so there is no complexity in hardware brands, etc. Phase 1 will not complete. Using pre-share/3des/sha/dh1, like we always have.
Thank you! Hopefully someone else has seen this.
