Hi i have different office branches connecting to a "master" OpenVPN node. then i have client machines that connect to that master too. -> this is the "first/outer" VPN, running with TUN and via UDP
after setting up the first connection. the clients should create a second/inner tunnel to the office branches, and this connection goes trought the first VPN. as the clients need to receive the broadcast traffic from the branches, and also the DHCP leases, i use TAP and UDP. and first that setup seemed to work fine. but after more testing it showed that some applications do not work, e.g. TCP connections inside the second tunnel cannot be established. it seems like the tunneled packets don't arrive in the right order at the endpoint. when i changed the "inner/second" tunnel to TAP and TCP, it seemed to work. before changing all the devices i would be happy to get some advice. which is the preffered way of such an setup? - TCP vs UDP for the outer/inner tunnel - compression/no compression for the tunnels what are the problems that could arise? bottlenecks? thanks for help, with this a little bit complicated openvpn setup (and no, the clients cannot directly reach the branches, so the two tunnels are needed :-( ). greets KoS ------------------------------------------------------------------------------ How ServiceNow helps IT people transform IT departments: 1.
