I tried natd -reverse and got a core dump due to infinite recursion.
alias.c in libalias has this rather amusing code:
int
PacketAliasIn(char *ptr, int maxpacketsize)
{
struct in_addr alias_addr;
struct ip *pip;
int iresult;
if (packetAliasMode & PKT_ALIAS_REVERSE)
return PacketAliasOut(ptr, maxpacketsize);
...
int
PacketAliasOut(char *ptr, /* valid IP packet */
int maxpacketsize /* How much the packet data may grow
(FTP and IRC inline changes) */
)
{
int iresult;
struct in_addr addr_save;
struct ip *pip;
if (packetAliasMode & PKT_ALIAS_REVERSE)
return PacketAliasIn(ptr, maxpacketsize);
...
I noticed also that PKT_ALIAS_REVERSE is not documented int libalias.3.
What I actually want do to is redirect connections from my internal network
to a certain external host to an ssh port (on 127.0.0.1). What's a good way
of doing this?
This is on reasonably up to date current and 3.2 stable.
