My routers fierwall has blocked input from the WWW Now I have the following situation if a PC or mobil phone tryes do connect via WWW to the EZL70. The EZLs state bevore a connection(yellow LED blinks): ezTCP/LAN Rev. 1.1F 8MHz UPTIME: 0 days, 00:00:07 ---------------------------------------- MAC ADDRESS: 00:30:f9:05:04:72 IP ADDRESS: 192.168.2.110 SUBNET MASK: 255.255.255.0 GATEWAY: 192.168.2.1 [TCP LISTEN 1470] ---------------------------------------- Serial RX bytes: 0 Serial TX bytes: 0 ---------------------------------------- during a client has connected (yellow LED ligths): ezTCP/LAN Rev. 1.1F 8MHz UPTIME: 0 days, 00:01:58 ---------------------------------------- MAC ADDRESS: 00:30:f9:05:04:72 IP ADDRESS: 192.168.2.110 SUBNET MASK: 255.255.255.0 GATEWAY: 192.168.2.1 [TCP CONNECTED 193.254.160.82:50125] ---------------------------------------- Serial RX bytes: 0 Serial TX bytes: 0 ---------------------------------------- after external hang up(yellow LED blinks):: ezTCP/LAN Rev. 1.1F 8MHz UPTIME: 0 days, 00:05:22 ---------------------------------------- MAC ADDRESS: 00:30:f9:05:04:72 IP ADDRESS: 192.168.2.110 SUBNET MASK: 255.255.255.0 GATEWAY: 192.168.2.1 [TCP LISTEN 1470] ---------------------------------------- Serial RX bytes: 0 Serial TX bytes: 0 ---------------------------------------- I think the connection is a deadlock, but I dont know why? The client waits for what? I wait on a HTTP-request from the clients browser, that I can respons. I can not do anything? To which time of the 3 state TCP connecting for the EZL is the connection established and the yellow LED lights full. 1. after the ACK from client or 2. earlier, if the client sends the request. Have you an inspiration what is here happen. Greetings from germany H.
