broadcast over gre tunnel?
Hello, I connected the network 192.168.1.0 with 192.168.2.0 over the internet trough a GRE-Tunnel.

The 192.168.1.x''s default gateway is 192.168.1.250 wich routes traffic destinated to

MTU issue when using GRE over tinc
[Disclaimer : I'm not a network engineer] Hi, In a setup where OpenVSwitch is used with GRE tunels on top of an interface provided by tinc, I'm experiencing MTU problems and I'm not sure how to fix them. The manifestation of the problem is, from the user point of view, communication hang. And using "tcpdump -i there" displays lines such as : 18:54:00.345666 IP

Yikes! Routing issues!
We switched over from a bordermanager firewall to a shorewall firewall. Some stuff is not working now. I realized that I had not created the route for the network that is not working however once I created it, it still didn''t work. Most of our network is fine however some pieces are not working.

transport multicast traffic through a gre tunnel.
Hi All, As it is written in the "Linux 2.4 Advanced Routing HOWTO" GRE tunneling has some benefits compare to IP-in-IP, on of it benefits is the ability to transport multicast traffic through a GRE tunnel. I used the mrouted daemon and I know that the daemon supports tunneling but I don''t want to use its tunneling method. Assuming I have gre0 as my tunneling device I did the

equalize / ecmp not working as expected in 2.6 vs 2.4
Hi, With kernel 2.4 I was able to use equalize to send our outgoing packets to two different routers (our isp supports this setup), like this: ip route add default src ip.a.dd.rr equalize nexthop via <router1> weight 1 nexthop via <router2> weight 1 The two routes were used equally on a per packet basis, not per flow or per cached route, but per packet, each line has 800k upload

shorewall suddenly dropping all from outside
Hi List, I read this list for nearly two years and learnt a lot, but now i have a very strange problem I can''t solve.. I have a firewall machine running Debian, which connects a small office to the internet via a DSL-line (with pppoe) and which is running Shorewall. It allows all outbound traffic and accepts pptp, openvpn and ssh-connections (on a non-standard port) from the internet.

OpenVPN tun Interface
I have a zone "rw" defined as tun0 in interfaces. From that zone, pings to zone "loc" succeed but pings to remote networks (On IPsec VPNs) are rejected in the all2all chain. From my point of view, these pings should be in the rw2cctc chain. (rw to cctc is ACCEPTed in policy.) I must have a hole in my config, where would it be? Thanks, A.

May be I''m wrong if someone got a solution, I may be interrested. I''ve also tryed ebtables, but nothing to prevent arp
