Subject: Re: Some kernel compilation errors
I am having new problems with NAT. Not sure to send a new mail for this.
When I add the module iptable_nat I got this error:
x_tables: exports duplicate symbol xt_free_table_info (owned by kernel).
I compile nat as module, but it seems as it were compiled with the kernel.
Also a cat in /proc/net/ip_tables_targets gives :
- TTL
- TCPMSS
- LOG
- TOS
- REJECT
- MARK
- MARK (duplicate?)
- ERROR
I use some container as routers, inside of them I use NAT to give internet
to some of them. This was working on proxmox (after some changes, that I
cant remember right now).

I use a lot OpenVz container with bridges. I use bridges as virtual
switches. the kernel option is CONFIG_BRIDGE, that is disabled by default.

yes that is right. I think is a dependency of VPS filesystem not sure. After
apply the Owl patch compilation was successful. I will try to reproduce it.
