Multiwan failover between two sites via P2P Leased line.



  • I’m currently trying to model the setup I have in GNS3 and implement Failover.
    I have two sites connected via a dedicated 1Gb point to point leased line.
    Site WS has a 1Gb leased line to the internet
    Site HH has a 100Mb leased line to the internet

    I am trying to setup failover between the two sites via the P2P leased line.
    If I loose access to internet at either site, after a short while the P2P gateway becomes the default and data is routed over it, I can see the LAN on each side however I am unable to get out to the internet via the router on the other end of the P2P connection.
    I’m pretty sure it something very simple I’m missing but I really can’t see what it is at the moment and would appreciate some help.

    The current settings are
    WS Site
    Interfaces
    WAN EM0: xx.xx.xx.xx/28 GW_WAN Static IP of the 1GbLL Router
    WSP2PHH EM1: 10.10.100.1/24 GWAY 10.10.100.2
    LAN EM5: 192.168.1.1/24 DHCP 192.168.1.10-200

    Gateways:
    WS GW_WAN(Default) Static IP of the 1GBLL router
    WS GW_OPT1 10.10.100.2
    Static routes
    192.168.2.0/24 GW_OPT1 – 10.10.100.2 Interface WSP2PHH
    Gateway Groups
    WSP2PHHFailover
    GW_OPT1 Tier 1 Interface address
    GW_WAN Tier 1 Interface Address

    LAN Firewall rules
    IPV4 * LAN net * * * WSP2PHHFailover none Default allow LAN to any

    Advanced Settings.
    Networking:
    Reset all states if WAN IP Address changed.
    Miscellaneous
    Load balancing: Use Sticky Connections, enable default gateway switching
    GW Monitoring Flus all states when Gateway goes down and Do not create rules when gateway is down

    The HH site is an identical setup with these differences.
    Interfaces:
    HHP2PWS EM1: 10.10.100.2/24 GWAY 10.10.100.1
    LAN EM5: 192.168.2.1/24 DHCP 192.168.2.10-200
    Gateways:
    GW_OPT1 10.10.100.1
    Static routes
    192.168.2.0/24 GW_OPT1 – 10.10.100.2 Interface WSP2PHH

    This should read...
    192.168.1.0/24 GW_OPT1 - 10.10.100.1 Interface HHP2PWS
