I have a central site which I can remote into using Remote VPN (ipsec). From the central site, i also have a permanent VPN to a branch location which i use for backups etc. Both Central and Remote routers are 887sec
Point is, rather than create Remote VPN on the branch site, i need to beable to route or reach the branch network from the remote location wherever that may be.
Hairpinning is thrown around as something i need to do but 1 - i'm not overly familiar with the concept and 2 - i'm not sure it's even allowed or possible on the 887's?
Right now, i have the branch subnets being advertized to the central site via eigrp, i've updated the allowed/denied access list, added the route to the no nat access list, updated/verified the eigrp network commands. All routes are being advertized as expected but just can't forward traffic to the branch from the remote site.
Could anyone shed some light?
I haven't included config as hoping the theory you throw at me will start some other thought processes but if you need it, can put some up
