XG 105 IP Address / gateway IP address confusion

Gabriel Manea

Hi!  New to XG but worked with SonicWALL, IPFire, etc. and confused as to the gateway IP.  The scenario is usually Comcast for business with 5 IPs and, for example, the Comcast router is first with the SonicWALL after it configured on the WAN side with one of the fixed IPs and the gateway IP in the SonicWALL configuration being the Comcast router's WAN IP.  I am confused as to what should be the IP Address and the gateway address on the Sophos? As, mentioned I would assume the IP Address would be one of the 5 available WAN fixed addresses and the Gateway IP would be the Comcast router's WAN IP but it does not work!  Any help would be appreciated!

    Gabriel,

    if you are swapping a firewall with another one, pay attention with mac-address and arp table. It can require even days before the same Ip address can be configured on the same appliance because router keep the mac-address until 2 days.

    You should use the same configuration used on Sonicwall. Contact your ISP and ask for an arp-table reset.

    Regards
