we are connecting Cisco 887VA router with various other Non-Cisco routers.
VPN tunnels are up and we can ping devices on the remote network through the VPN.
However, we have a few devices (on the Cisco lan) that provide a web interface (NAS etc) and these are not accessible over the VPN, the connection seems to just hang like its waiting for a response but it never gets one and eventually the browser times out.
Strangely, if I request a page that does not exist from the NAS (eg. http://192.168.3.x/test) I will receive a 404 error so it is kind of working.
Similar problems with SMB, if I access \\192.168.3.x I can list the content (4 items) but if I go into one of those folders (containing 10+ items) it hangs and eventually gives up.
I have tried adjusting MTU and MSS with no change.
Any ideas cause I'm running out of hair
My config is attached, it is most likely a mess as this is my first Cisco device so please go easy
