Hi all, don't know what the requirements are but I want to let you know I'm in condition to contribute with success cases for working S2S VPN from CP's R80.10 to Cisco ASA 5505(8.3) and/or Fortigate 600c(OS 5.2.4).
The S2S to Cisco ASA was fully developed by us (also we do a VPN from a CP 1450 R77.20.80 to the same ASA), but to the Fortigate was done by other people on the other side (maybe the next year will have some Fortigate here to play around).
Also the S2S to the Fortigate is a kind of a tricky one, as on the other side they have same subnets as we do, so we've to do some weird static NAT rules to make it work and don't overlap encryption domains.
Let me know how can I help the community with this, thanks
