I have doing a lot of research regarding error 14147 and 21265 on the internet. I got these errors twice a day and the internal netwrok cannot access external, I fix the problem restarting the machine but the users are getting annoying due the conexion problems. My internal network is 192.168.30.x, ISA server is 192.168.30.2, it is connected to a router with static public IP address. All the computers in the internal network have the ISA Server as defatult gateway. The error messages I got are following: Event Source: Microsoft Firewall Event Category: None Event ID: 21265 Date: 28/02/2011 Time: 08:31:03 a.m. Type: Error User: N/A Computer: HIPPOISA The routing table for network adapter WAN includes IP address ranges that are not defined in the array network Externa to which it is bound. As a result when packets go in/out via this network adapter and they are from/sent to the IP address ranges listed below they will be considered spoofed and will be dropped. To resolve this issue add the missing IP address ranges to the array network. The following IP address ranges will be dropped as spoofed: Interna:192.168.0.0-192.168.29.255,192.168.31.0-192.168.255.255; Event Source: Microsoft Firewall Event Category: None Event ID: 14147 Date: 28/02/2011 Time: 08:31:03 a.m. Type: Error User: N/A Computer: computer name ISA Server detected routes through the network adapter Local that do not correlate with the network to which this network adapter belongs. When networks are configured correctly, the IP address ranges included in each array-level network must include all IP addresses that are routable through its network adapters according to their routing tables. Otherwise valid packets may be dropped as spoofed. The following ranges are included in the network's IP address ranges but are not routable through any of the network's adapters: 192.168.0.0-192.168.29.255,1

Solved ISA 2006 Lost Internet Connectivity Posted on 2013-09-10 MS Forefront-ISA 1 Verified Solution 1 Comment 1,080 Views Last Modified: 2013-10-08 Hi there, Everyday in the morning, the company is losing Internet connectivity. In order to restore it, sometimes i can simply restart the firewall service, sometimes I need to disable/enable the internal NIC, and sometimes i need to reboot. When this happens I cannot ping the internal IP but I can RDP to the box, which is strange. This all seems to be related to the number of connections to the DC but i cannot be sure. Things I've tried: - Rebuild the cache file - Disable the Flood Mitigation Settings - Increase the timeout for Connectivity Verification (see Error below) None of this seems to do anything. Here are some log and event viewer entries i'm seeing: Event Viewer: EventID: 14147 ISA Server Detects routes through the network adapter that do not correlate with the network to which this network adapter belongs... EventID: 21265 The routing table for the network adapter Internal includes IP address ranges that are not defined in the array-level network. EventID: 1055 Windows cannot determine the computer name. Group policy aborted. The user in this case was the ISA admin account. After this error, the internet was lost. EventID: 15120 The number of concurrent TCP connections from the source IP address .... exceeded the configured limit. (This seems to come up after a firewall service restart) ISA Alerts I get alot of Concurrent TCP connections from One IP address alerts. Systems do not seem to be compromised though as the IP address is never consistently the same. Granted they are DHCP so they may just be pulling different addresses. One of them is my machine actual
