Hai,
i have MPLS (BGP) connection for DATA only and Internet through one link. its terminated on CISCO Router both internet and BGP to 11 Branches working perfectly.
now we are testing Sophos UTM at HO replacing the Cisco router.everything seems to be working perfect but after some time Internet has problem unable to resolve DNS. Internet is not stable.
traceroute from one PC show correct path (through Public IP) when internet is working but when internet is not working traceroute form the same PC shows the traffic is hitting BGP Interface IP then neighbor its looping between this two IP.
i tried different dns options but no help. when i connect back to Cisco Router everything seems to be stable.
