- What do these ALG setting on my router mean, and what is ALG?
Firewalls with NAT enabled translate IP addresses and TCP UDP ports within the corresponding headers But some protocols also send the client's or server's address inside packets themselves – for example, yes, the same FTP does this (in active mode the client sends its own address, in passive mode the server does)
- Can someone help me understand ALG and VPN settings on my router?
TFTP ALG - To allow TFTP clients and servers to transfer data across NAT, click Enable H323 ALG - To allow Microsoft NetMeeting clients to communicate across NAT, click Enable RTSP ALG - To allow some media player clients to communicate with some streaming media servers across NAT, click Enable
- For better security, should I enable or disable these ALG firewall options - Router? - Super User
Application Level Gateway (ALG) Configuration Here you can enable or disable ALGs Some protocols and applications require special handling of the IP payload to make them work with network address translation (NAT) Each ALG provides special handling
- Why SIP-ALG in routers and modems? - Super User
A SIP ALG router rewrites the REGISTER request so the proxy doesn't detect the NAT and doesn't mantain the keepalive (so incoming calls will be not possible) Breaking SIP signalling: Many of the actual common routers with inbuilt SIP ALG modify SIP headers and the SDP body incorrectly, breaking SIP and making communication just impossible
- FTP disconnects after entering passive mode b c packets are lost
I disabled something called "NAT ALG" (Application-level gateway) and the FTP client and server started communicating normally in passive mode again Apparently this protocol snooping causes problems for a lot of people
- Cannot connect to FTP server from external host - Super User
The FTP ALG has to watch for what port the server told the client to connect on, and then automatically create a temporary port forwarding entry to allow that connection to get to the server Basically, Passive mode FTP, which is great when the client is behind a NAT, is a big problem when the server is behind the NAT
- networking - Why disable NAT passthrough? - Super User
NAT from external network to inside is disabled by default because of security The VPN pass-through isn't directly same as NAT VPN is used to join an external network so, that everything between you and the external network thinks that you are part of the other network (Where you have connected with VPN)
- What type of NAT does iptables MASQUERADE implement?
The NAT behavior of netfilter can be classified as "non-deterministic" NAT in terms of RFC 4787, whether we specify "--random" or not netfilter internally manages connections by "address and port dependent" mapping and just avoid assigning the same port for connections from different local addresses to the same destination
- Port-forwarding in router ZTE ZXHN F660: hidden settings
In my company, we have a ZTE ZXHN F660 router, and we need to do a port-forwarding to access a DB allocated in one of our machines through public IP We have login into router admin page (visit pu
- networking - Accessing LAN device using port triggering from a “mock internet” on the WAN port - Super User
In the web GUI of the TP-Link router, under the section “NAT”, which of the following best accomplish what I’m trying to do? Other than the two already covered above: "UPnP" doesn't do anything on its own – it only lets a LAN computer request (using UPnP's IGD protocol) that the router add a 'virtual server' 'port forwarding' entry for some port
