We have two subnets, say 'domA' (192.168.0.0/24) and 'domB' (10.10.0.0/16). These subnets are connected through the router 'router01'. One server 'base01' has two network cards, configured to domA and domB subnets respectively.
Now let's consider a host host01.domA (192.168.0.5) trying to connect to base01. host01.domA has no problems when connecting to base01.domA, but host01.domA is not able to connect to base01.domB.
The router is working fine because host01.domA is able to connect to other hosts on domB that are not multi-homed.
What is interesting is that we never had this problem until we installed Ubuntu on base01. We have been using OpenSuSE until now without this particular problem.
When I look at tcpdump on base01.domB for ping requests, I see the incoming requests, but there is no echo going back.
I hope I am able to explain my problem. I would be more than willing to give more details if needed.
I would really appreciate if someone can give me some idea as to where I should be looking to find the solution.
I'm new to this forum, so please be gentle !

IPSEC_SAMEADDR(3) Library Functions Manual IPSEC_SAMEADDR(3)NAME
ipsec_sameaddr, ipsec_addrcmp, ipsec_samesubnet, ipsec_addrinsubnet, ipsec_subnetinsubnet, ipsec_subnetishost, ipsec_samesaid,
ipsec_sameaddrtype, ipsec_samesubnettype - do comparisons for addresses, subnets, SA IDs and address families
SYNOPSIS
#include <freeswan.h>
int sameaddr(const ip_address *a, const ip_address *b);
int addrcmp(const ip_address *a, const ip_address *b);
int samesubnet(const ip_subnet *a, const ip_subnet *b);
int addrinsubnet(const ip_address *a, const ip_subnet *s);
int subnetinsubnet(const ip_subnet *a, const ip_subnet *b);
int subnetishost(const ip_subnet *s);
int samesaid(const ip_said *a, const ip_said *b);
int sameaddrtype(const ip_address *a, const ip_address *b);
int samesubnettype(const ip_subnet *a, const ip_subnet *b);
DESCRIPTION
These functions do various comparisons and tests on the ip_address type and ip_subnet types.
Sameaddr returns non-zero if addresses a and b are identical, and 0 otherwise. Addresses of different families are never identical.
Addrcmp returns -1, 0, or 1 respectively if address a is less than, equal to, or greater than b. If they are not of the same address fam-
ily, they are never equal; the ordering reported in this case is arbitrary (and probably not useful) but consistent.
Samesubnet returns non-zero if subnets a and b are identical, and 0 otherwise. Subnets of different address families are never identical.
Addrinsubnet returns non-zero if address a is within subnet s and 0 otherwise. An address is never within a subnet of a different address
family.
Subnetinsubnet returns non-zero if subnet a is a subset of subnet b and 0 otherwise. A subnet is deemed to be a subset of itself. A sub-
net is never a subset of another subnet if their address families differ.
Subnetishost returns non-zero if subnet s is in fact only a single host, and 0 otherwise.
Samesaid returns non-zero if SA IDs a and b are identical, and 0 otherwise.
Sameaddrtype returns non-zero if addresses a and b are of the same address family, and 0 otherwise.
Samesubnettype returns non-zero if subnets a and b are of the same address family, and 0 otherwise.
