NF,
Setting up iptables with PREROUTING to change the destination
and forward the
packet and POSTROUTING to change the source address.
PREROUTING works fine.
POSTROUTING changes the source address and I get the udp
packets correctly
but then I get an ICMP destination unreachable error message.
The packet is reaching the destination and the source address is
changed correctly.
If I take out the POSTROUTING call the ICMP messages disappear
but the
messages don't have the modified source address because POSTROUTING has been
turned off.
Tried many variations on the format and added FORWARDing entries
but nothing
seems to stop the generation of ICMP packets when POSTROUTING is
implemented.
Using linux 2.4-20.
"ip_forward" is set to 1.
