I'm trying to set up a GRE Tunnel from a Cisco SRP527W Router to a Mikrotik RouterBoard.
The Cisco end is head office, whereas the Mikrotik is at a remote site.
The Mikrotik sits behind the ADSL router at the office with all ports for VPN forwarded to it.
As the Cisco SRP has no CLI it's harder to set up than traditional methods.
Tunnel No: 1
Wan interface: ADSL
Destination I.P: Remote Site WAN
Remote IP Address/Sbunet Mask: 172.20.10.1/29
Local address: 172.20.10.2/29
Remote Address: Head Office WAN I.P
The Mikrotik has the I.P address also assigned in the I.P > Addresses list and is assigned to the GRE tunnel interface.
On the Mikrotik I have created a NAT Masquerade rule to point the Head Office Subnet.
From the Mikrotik, pinging the 172.20.10.1 only shows a timeout...
Any ideas where I may have missed something???
