Hi,
I’ve recently got myself two Mikrotik routers, to link two remote networks together. The idea was to create a single network with one public IP. I set up the to MTs to connect to the internet through the existing ADSL modems at each end. I then set up a VPN link to a remote hosted server on each of the routers. I set this link up as the default route, forcing all traffic over the VPN and out the same public IP. I then set up an EoIP tunnel between the two routers via the VPN server. So far so good - both sites can see and talk to eachother, and share the same broadcast range but use different address blocks at each end (each router is the DHCP server for it’s local clients, and the default route for them. DHCP traffic over the EoIP is blocked - this allows internet traffic to take the fastest route out to the web, yet local traffic to get to the right devices)
So, heres the problem… No matter what I try, certain websites just don’t load - for the most part, the internet is fine. you can google, load sites like this one etc, access IMAP email, but some services and sites just hang forever (speedtest.net is a good example) I had thought this might be a max MTU issue, based on the fact the MTU of a PPTP VPN is less, but no matter what I set the MTU of any interface to, i cannot get the sites to work… the best I can do is break the entire connection if I lower the MTU too much.
A direct connection to the VPN from my macbook has no issue with these sites - all traffic works (and I can connect back to the MT devices through that VPN)
So im here in desperation, hoping someone can see where i’ve gone wrong! Thanks for taking the time to help me
