SG 310(firmware 9.355-1) appliance when installed between a cisco 2960(vlan801) and cisco router 2911 Default gateway (2911 connected to 2960 on WAN connection). SG310 blocks the internet and cannot even ping the DG which is cisco 2911.
Here is the net config: My subnet is 10.10.11.0/24 cisco 2960 (vlan 801) is connected to router cisco 2911 connected via internet WAN connection, everything works great. The moment SG 310 (in a bridge) is introduced between the switch 2960 and the router 2911 it blocks all protocols, internally i can see the flowing firewall logs and mostly it is blocking external traffic, drop packets TCP etc. Eth1 WAN port on SG310 is connected to the internet connection (WAN from the internet to my router 2911), and Eth0 LAN port on SG310 goes into my cisco switch 2960. This does not work. Sophos techs have checked all the internal config on the SG310 like firewall etc and cannot detect any running logs as the connection drops the mement SG310 is introduced. Need help
