Dan, Thanks for the info. I did a Google groups search to see if I could find details of your previous work, but didn't find it. The system I am working with is i386, 2.4.20-8 for kernel and 2.4.1-10 for pppd. Any details you can share about how to progress will be greatly appreciated.

You can't bridge ppp0 because Linux doesn't support BCP without patching the kernel and pppd. I posted such patches about 8 months ago. There have been a few enhancements and bug fixes since then. Would you like me to put new ones together? The drawback is that they would apply to kernel 2.4.21-pre4 (PowerPC) and pppd 2.4.1, not the latest and greatest. Would that work for you? -- Dan Eble <dane@xxxxxxxxxx> _____ .

Yes, here's the dialog # brctl addbr bridge1 # brctl addif bridge1 eth0 # brctl addif bridge1 ppp0 br_add_interface: Invalid argument Note - it doesn't seem to matter if I set any of the interfaces down or to 0.0.0.0. It appears as though it really doesn't like ppp interfaces. BTW, making all ethernet bridges works just fine, so it's not like bridging itself doesn't work. Thanks again.

The command in the subject line, brctl addif bridge1 ppp0, returns an br_add_interface: Invalid argument response. I've seen several others have run in to this via google groups, but I didn't see any responses detailing the cause of the corrective action. Please let me know if what I am trying is unsupported and won't work, or if there some kind of likely operator error that I'm locked in. Linux install: Red Hat 9 Brctl: installed from rpm on website Thanks and regards, John Wise john.wise@xxxxxxxxxx
