Hi, The private adresses (192.168.254.0/255.255.255.0) of my network are sent dynamically by dhcp on my network. The dhcp server is on the firewall which address is 192.168.254.1/255.255.255.255 (this address is static). I''ve got a rsync server on this network which is on a separe server.

Whenever I add or remove a DNAT rule such as: iptables -A PREROUTING -p tcp --dport 80 -j DNAT --to-destination 192.168.0.1 there is sometimes a delay before the correct nat''ing is done. Can anyone tell me why this is? Is it something to do with caching of routing tables? If so, is there a way to clear them to ensure that the rule takes effect immediately? I am building a simple

If I want to use DNAT to forward data destined for a port on the firewall to a different port on a machine behind the firewall, is this this syntax correct? DNAT net:3599 loc:192.168.0.10 tcp 22 I can find bits at each end in the docs but not both ends. TIA richard

I have been trying to get DNAT to work and I actually have succeeded too, however, not how I thought it would work when reading through the documentation. 1. No matter what I do I cannot get DNAT to work unless I have an entry in eiter the nat or the proxyarp file. Is that really how it''s supposed to be? I can''t find anything about it in the documentation. 2. Also, in the

Hi All, I use rather old Shorewall 3.2.6 and I know it''s no longer supported. I haven''t been updating the software because it works as intended until now. The problem is a simple DNAT rule. I actually have around 8 DNAT rules and they all work just fine. Here is what I want to achieve. I have a SMTP server in my LAN (lets say address 192.168.1.10). The SMTP daemon listens on

Hello, I''m trying to setup DNAT to forward to a PPTP Server behind Shorewall. I setup the PPTP rules per your documentation with tcp port 1723 and Protocol 47 DNAT to my PPTP Server in the local zone. Looking at the logs it is dropping the connection going to port 1723. It is also dropping UDP port 1701, don''t know if it is of any significance. I looked at FAQ 1a and b and the

So I finally got shorewall up with my linux box, which pipes out to a switch, and then my machines... Problem now is on my one machine, I have a remote admin server running on port 4899... So since I''m using masq, I added a DNAT entry in my rules instead of an ACCEPT DNAT net loc:192.168.1.3 tcp 4899 So when I try to access my remote admin using my external IP, even from inside, I

Hello List. I''m new here, and am staring off with a pretty common question, i think. I want to have my router DNAT incomeing connections for other IP''s than it''s WAN IP. In my other setup, just adding that IP as Destination Address was enough. But that was a bit older Version of Shorwall. In my new Setup, Shorewall 2.0.7 Debian Sarge, i have this line: DNAT

Hi, I have a rule: DNAT net dmz:a.b.c.d tcp 25 - k.l.m.n The problem: I want to DNAT port 25, 143, 110 k.l.m.n is alternate public ip (using vrrp, just like alias) Can I abridge the above line using macro, instead of writing 3 separate lines? I can do: MailPorts/DNAT net dmz:a.b.c.d But this refer to the physical public ip I have more elaborate requirement to forward around 20

I need to access externally (via Internet) one device in internal network which has no default gateway configured. As the device doesn''t have default gateway, the response to SYN (ie, SYN/ACK) don''t come back to Internet. What I need is a setup to make this connection appears to come from firewall''s internal IP address instead of the public IP of originating requester
