I have an ASA 5510 connected with the modem of the ISP which is bridged. To this ASA I have connected a cisco switch SF300 for the inside network with a static IP 192.168.0.205. The internet is intermittent when connected directly with the switch but when I connect a router with static IPs with the switch, the internet works well. The following is the running configuration of the Cisco ASA 5510.


Result of the command: "sh run"
