Bridging problems RHEL - packets not forwarded by bridge?

MartinB-swe · Post by **MartinB-swe** » Wed Jul 06, 2011 2:09 pm

I'm stuck with a bridging setup.
I've successfully set up a POC based on Debian and transferred the config and scripts to a RHEL installation.

The bridged LAN is a subnet containing three things for now:
* A client connected via openvpn
* The OpenVPN server via br0/eth1
* A Cisco router with minimal config

* The tunnel comes up.
* The client is able to ping/SSH the br0-interface of the server
* The client is UNABLE to ping the router on the other side of the bridge
* When masquerading the client to the address of br0 we can connect through OpenVPN (not an option)

* The server can ping both the client and the router so I assume the bridge is properly configured.

etho (public interface) got an ip address
br0 has an ip address on the internal network
eth1 and tap0 has no ip addresses.

I and a colleague have been staring on this setup some hours a day for a couple of days now and we feel that we are stuck.

We have compared the sysctl -a output and there are differences we've tried to change but no luck.
The iptables rules is flushed and default policy set to ACCEPT.

The RHEL machine is running in VMware, the Debian POC machine is a normal, physical desktop machine.

At my previous employer I've ran a similar setup, also on a virtual machine but on Debian.
Rigid policies forbids us to try Debian at my new employer.

Can anyone help? Google gives a minimum of answers.
Hints like switch to routing is not an option since we are running public ip addresses on the internal interface and can't afford to lose up to four adresses for each connection.

It feels like it's make no sense in posting config files here but I gladly post whatever you want, just tell me what to post.

rhel comes with selinux

what is the output of sestatus?

can you post configs?logs?

please give as much info as you can..

also

you mentioned that this is a vm...
how did you setup their nics? bridged? NAT?

I have no control over the ESX server itself but the hardware interface runs as a dot1q trunk, in the ESX config we create a "physical" interface assigned to the VLAN and assigns it to the virtual machine (as it is expected to be by the VMware-book).
Our host doesn't see anything tagged at all, it's just plain vanilla interfaces (and it worked fine at my former employer also running ESX)

hi there,

is ipforwarding enabled?

Michael.

Yes, but i'm in doubt that this is needed on a bridge.

Post by **maikcat** » Thu Jul 07, 2011 9:13 am

can you please take a look here

topic8408.html

also into your server-bridge directive use your router ip instead of br0 interfaces..

Michael.

topic8408: not applicable, no routes are lost.
That machine seemed to have only one physical interface, this one has two.
Besides that, the server is able to reach both the local resources (on the same LAN) AND the openvpn client. The client also gets an ARP reply from the router and I suspect it's some kind of spoofing protection that hits us but we are out of ideas.

If we create an iptables MASQ rule it works but then we lose track of the individual ip addresses later on.

I tried to change the server-bridge even if I find it in conflict with the documentation and there is no change, OpenVPN starts, the tunnel comes up and works as before but i can't reach the other side of the bridge.

I also push the fact that this setup works great on a Debian installation (and it looks like topic8408 runs one some kind of Debian or derivate?)

I'm very confused about this.

Post by **maikcat** » Thu Jul 07, 2011 11:22 am

which ver of rhel are you using?

openvpn version ?

Michael.

ps: i will try to resetup bridge scenario asap...

Post by **maikcat** » Thu Jul 07, 2011 1:00 pm

i retest my setup:

server centos 5.5 x86 + openvpn 1.1.4 (from rpmforge repo)

server.conf

proto udp

server lan ip 192.168.179.20 (router 192.168.179.1)

used there commands from cli:

openvpn --mktun --dev tap0
brctl addbr br0
brctl addif br0 eth0
brctl addif br0 tap0
ifconfig eth0 promisc 0.0.0.0 up
ifconfig tap0 promisc 0.0.0.0 up
ifconfig br0 192.168.179.20 netmask 255.255.255.0 broadcast 192.168.179.255 <--here i lost gateway
route add default gw 192.168.179.1
service openvpn start

cat /proc/sys/net/ipv4/conf/eth0/proxy_arp reports 0
iptables is disabled
selinux is disabled
ip forwarding is enabled

client winxp sp3 with openvpn 2.1.3

client
proto udp

and it works!....

OpenVPN:
openvpn.x86_64, 2.1.4-1.el5
bridge-utils.x86_64, 1.1-2

Red Hat Enterprise Linux Server release 5.6 (Tikanga)

It's interesting that it works for you too, this Red Hat machine is the first one i've ever had trouble with.
OpenVPN is stable, even on my WRT-56GL

Edit: I assume you were testing your client from an another subnet than 192.168.179.0 so you did'nt contact the router directly?
