I havbe a Little problem with a "TP-Link TD-W8980":
I have installed the current Version of OpenWRT. Then I have create to WLANs: Intranet and Guest.
To sepperate the WLANs I have create a VLAN and thgen I bridged the VLAN an the Guest-WLAN.
Now my Problem:
I can ping from the client in WLAN to the IP from the TP-Link-router
I can ping from the TP-Link-router to the firewall (end of the VLAN)
I become a dhcp-address from the firewall to the wlan-client
BUT: I cannot reach the firewall from the wlan-client. Ideas?
thank you all.
I found the error: the firewall are misconfigured by the administrator.
I can not understand why this produced so rare results in my openwrt router. According to the manufacturer, the firewall has an "intelligent" packet filter, which is supposed to detect attacks, but in my case, all requests to the network seem to have been blocked by the firewall.
