    Hallo Zeros,

    i would like to connect 2 location over VPN, but i won’t use normal routing i will use the fixed ethernetports so i can use the same subnet.

    I connect both sites with VPN, this is no problem, then i bridged on every side the VPN00 with ETH01.
    Then i connect a PC on side 2 but i can’t get any connection e.g DHCP or something else. Does the bridge net an IP?

    Have anyone ideas?

    Regards Mario

    yes , both bridges need an ip address belonging to the same subnet , eg. bridge00 (eth01,vpn00) siteA 10.128.0.1/24 , bridge00 (eth01,vpn00) siteB 10.128.0.2/24 .

    Hallo Jonatha,

    thank you for your reply, but it doesn’t work.
    I insert an ip adress from my network that i want to transfer to side b.
    Then 192.168.0.1/24 and 192.168.0.2/24 nothing works 🙁

    Any Ideas?

    ciao Mario

    Hi Mario , I tried some different vpn configs with ZS , L2L , L2L bridged , H2L , H2L bridged, all worked fine , my default firewall policy on both ZS is drop , ( input and forward chains ) , so everytime I needed to adjust the fw rules (sometimes on phisical ,,but almost everytime on virtual interfaces..) to permit traffic from/to end-points in the different configs…are your fw rules correct ? what the logs say ? you should be able to ping ( and arping , since the hosts are in the same broadcast domain) from hosts connected to ETH01 siteA to hosts hosts connected to ETH01 siteB and vice-versa , while the shared docs is a bit slow if you are using the vpn over internet ( in a lab enviroment , using the vpn over lan , obviously is a lot faster).
    Could you post the output of iptables -L ?
    ciao
